Political parties in the United States in the context of "Fourth Party System"

The Democratic Party is a liberal political party in the United States. Sitting on the center to center-left of the political spectrum, it is the world's oldest active political party, having been founded in 1828. Its main rival is the conservative Republican Party, and since the 1850s both have dominated American politics.

It initially supported Jacksonian democracy, agrarianism, and geographical expansionism, while opposing a national bank and high tariffs. Democrats won six of the eight presidential elections from 1828 to 1856, losing twice to the Whigs. In 1860, the party split into Northern and Southern factions over slavery. The party remained dominated by agrarian interests, contrasting with Republican support for the big business of the Gilded Age. Democratic candidates won the presidency only twice between 1860 and 1908 though they won the popular vote two more times in that period. During the Progressive Era, some factions of the party supported progressive reforms, with Woodrow Wilson being elected president in 1912 and 1916.

The Whig Party was a mid-19th century political party in the United States. Alongside the Democratic Party, it was one of two major parties from the late 1830s until the early 1850s and part of the Second Party System. As well as four Whig presidents (William Henry Harrison, John Tyler, Zachary Taylor, and Millard Fillmore), other prominent members included Henry Clay, Daniel Webster, Rufus Choate, William Seward, John J. Crittenden, and John Quincy Adams (whose presidency ended prior to the formation of the Whig Party). The Whig base of support was amongst entrepreneurs, professionals, Protestant Christians (particularly Evangelicals), the urban middle class, and nativists.

The party was hostile towards the ideology of "manifest destiny", territorial expansion into Texas and the Southwest, and the Mexican–American War. It disliked presidential power, as exhibited by Andrew Jackson and James K. Polk, and preferred congressional dominance in lawmaking. Members advocated modernization, meritocracy, the rule of law, protections against majority rule, and vigilance against executive tyranny. They favored an economic program known as the American System, which called for a protective tariff, federal subsidies for the construction of infrastructure, and support for a national bank. The party was active in both the Northern and Southern United States and did not take a firm stance on slavery, but Northern Whigs tended to be less supportive than their Democratic counterparts.

The Republican Party, also known as the Grand Old Party (GOP), is one of the two major political parties in the United States. It is the second-oldest extant political party in the United States after its main political rival, the Democratic Party. In 1854, the Republican Party emerged to combat the expansion of slavery into western territories after the passing of the Kansas–Nebraska Act. The early Republican Party consisted of northern Protestants, factory workers, professionals, businessmen, prosperous farmers, and after the Civil War also of black former juivu. The party had very little support from white Southerners at the time, who predominantly backed the Democratic Party in the Solid South, and from Irish and German Catholics, who made up a major Democratic voting bloc. While both parties adopted pro-business policies in the 19th century, the early GOP was distinguished by its support for the national banking system, the gold standard, railroads, and high tariffs. The party opposed the expansion of slavery before 1861 and led the fight to dismantle the Confederate States of America (1861–1865). While the Republican Party had almost no presence in the Southern United States at its inception, it was very successful in the Northern United States, where by 1858 it had enlisted former Whigs and former Free Soil Democrats to form majorities in nearly every Northern state.

With the election of its first president, Abraham Lincoln, in 1860, the party's success in guiding the Union to victory in the Civil War, and the party's role in the abolition of slavery, the Republican Party largely dominated the national political scene until 1932. In 1912, former Republican president Theodore Roosevelt formed the Progressive Party after being rejected by the GOP and ran unsuccessfully as a third-party presidential candidate calling for social reforms. The GOP lost its congressional majorities during the Great Depression (1929–1940); under President Franklin D. Roosevelt, the Democrats formed a winning New Deal coalition that was dominant from 1932 through 1964.

The Democratic Party is one of the two major political parties of the United States political system and the oldest active political party in the country. Founded in 1828, the Democratic Party is the oldest active voter-based political party in the world. The party has changed significantly during its nearly two centuries of existence. Once known as the party of the "common man", the early Democratic Party stood for individual rights and state sovereignty, and opposed banks and high tariffs. In the first decades of its existence, from 1832 to the mid-1850s (known as the Second Party System), under Presidents Andrew Jackson, Martin Van Buren, and James K. Polk, the Democrats usually defeated the opposition Whig Party by narrow margins.

Before the American Civil War, the party generally supported slavery or insisted it be left to the states. After the war until the 1940s, the party opposed civil rights reforms in order to retain the support of Southern white voters. The Republican Party was organized in the mid-1850s from the ruins of the Whig Party and Free Soil Democrats. It was dominant in presidential politics from 1860 to 1928. The Democrats elected only two Presidents during this period: Grover Cleveland (in 1884 and 1892) and Woodrow Wilson (in 1912 and 1916). Over the same period, the Democrats proved more competitive with the Republicans in Congressional politics, enjoying House of Representatives majorities (as in the 65th Congress) in 15 of the 36 Congresses elected owing largely to their dominance of the Solid South, although only in five of these they formed the majority in the Senate. Furthermore, the Democratic Party was split between the Bourbon Democrats, representing Eastern business interests, and the agrarian party elements representing poor farmers in the South and West. After the Republican landslide in the 1894 House elections, the agrarian element, marching behind the slogan of free silver (i.e. in favor of inflation), captured the party. They nominated William Jennings Bryan in the 1896, 1900, and 1908 presidential elections, although he lost every time. Both Bryan and Wilson were leaders of the progressive movement in the United States (1890s–1920s) and opposed imperialistic expansion abroad while sponsoring liberal reforms at home despite supporting racism and discrimination against blacks in government offices and elsewhere.

Nebraska (/nəˈbræskə/ nə-BRASS-kə) is a landlocked state in the Midwestern region of the United States. It borders South Dakota to the north; Iowa to the east and Missouri to the southeast, both across the Missouri River; Kansas to the south; Colorado to the southwest; and Wyoming to the west. Nebraska is the 16th-largest state by land area, with just over 77,220 square miles (200,000 km). With a population of over 2 million as of 2024, it is the 38th-most populous state and the eighth-least densely populated. Nebraska's capital is Lincoln, and its most populous city is Omaha, which is on the Missouri River. Nebraska was admitted into the United States in 1867, two years after the end of the American Civil War. The Nebraska Legislature is unlike any other American legislature in that it is unicameral, and its members are elected without any official reference to political party affiliation. Nebraska is one of only two states (Maine being the other) that divide electoral college votes by district, and is not winner-take-all.

Nebraska is composed of two major land regions: the Dissected Till Plains and the Great Plains. The Dissected Till Plains region consists of gently rolling hills and contains the state's largest cities, Omaha and Lincoln. The Great Plains region, occupying most of western Nebraska, is characterized by treeless prairie. Eastern Nebraska has a humid continental climate while western Nebraska is primarily semi-arid. The state has wide variations between winter and summer temperatures; the variations decrease in southern Nebraska. Violent thunderstorms and tornadoes occur primarily during spring and summer, and sometimes in autumn. The Chinook wind tends to warm the state significantly in the winter and early spring.

The Second Party System was the political party system operating in the United States from about 1828 to early 1854, after the First Party System ended. The system was characterized by rapidly rising levels of voter interest, beginning in 1828, as demonstrated by Election Day turnouts, rallies, partisan newspapers, and high degrees of personal loyalty to parties.

Two major parties dominated the political landscape: the Democratic Party, led by Andrew Jackson, and the Whig Party, assembled by Henry Clay from the National Republicans and from other opponents of Jackson. Minor parties included the Anti-Masonic Party, an important innovator from 1827 to 1834; the abolitionist Liberty Party in 1840; and the anti-slavery expansion Free Soil Party in 1848 and 1852. The Second Party System reflected and shaped the political, social, economic and cultural currents of the Jacksonian Era, until succeeded by the Third Party System.

The Third Party System was a period in the history of political parties in the United States from the 1850s until the 1890s, which featured profound developments in issues of American nationalism, modernization, and race. This period was marked by the American Civil War (1861–1865), the Emancipation Proclamation and the end of slavery in the United States, followed by the Reconstruction era and the Gilded Age.

It was dominated by the new Republican Party, which claimed success in saving the Union, abolishing slavery and enfranchising the freedmen, while adopting many Whig-style modernization programs such as national banks, railroads, high tariffs, homesteads, social spending (such as on greater Civil War veteran pension funding), and aid to land grant colleges. While most elections from 1876 through 1892 were extremely close, the opposition Democrats won only the 1884 and 1892 presidential elections (the Democrats also won the popular vote in the 1876 and 1888 presidential elections, but lost the electoral college vote), though from 1875 to 1895 the party usually controlled the United States House of Representatives and controlled the United States Senate from 1879 to 1881 and 1893 to 1895. Indeed, scholarly work and electoral evidence emphasizes that after the 1876 election the South's former slave centers, which before the emancipation of Republican-voting African Americans was electorally dominated by wealthy slave owners who made up the southern base of Whigs, Know Nothings and Constitutional Unionists, began realigning into the Democratic Party due to the end of the now unpopular Reconstruction efforts; this new electoral base for the Democrats would finish realigning around 1904.

The Democratic-Republican Party, known at the time as the Republican Party (also referred to by historians as the Jeffersonian Republican Party), was an American political party founded by Thomas Jefferson and James Madison in the early 1790s. It championed liberalism, republicanism, individual liberty, equal rights, separation of church and state, freedom of religion, anti-clericalism, emancipation of religious minorities, decentralization, free markets, free trade, and agrarianism. In foreign policy, it was hostile to Great Britain and in sympathy with the French Revolution and Napoleonic Wars. The party became increasingly dominant after the 1800 elections as the opposing Federalist Party collapsed.

Increasing dominance over American politics led to increasing factional splits within the party. Old Republicans, led by John Taylor of Caroline and John Randolph of Roanoke, believed that the administrations of Jefferson, Madison, and Monroe—and the Congresses led by Henry Clay—had in some ways betrayed the republican "Principles of '98" by expanding the size and scope of the national government. The Republicans splintered during the 1824 presidential election. Those calling for a return to the older founding principles of the party were often referred to as "Democratic Republicans" (later Democrats) while those embracing the newer nationalist principles of "The American System" were often referred to as National Republicans (later Whigs).

The Libertarian Party (LP) is a political party in the United States. It promotes civil liberties, non-interventionism, laissez-faire capitalism, and limiting the size and scope of government. The world's first explicitly libertarian party, it was conceived in August 1971 at meetings in the home of David Nolan in Westminster, Colorado, and was officially formed on December 11, 1971, in Colorado Springs. The organizers of the party drew inspiration from the works and ideas of the prominent Austrian school economist Murray Rothbard. The founding of the party was prompted in part due to concerns about the Nixon administration's wage and price controls, the Vietnam War, conscription, and the introduction of fiat money.

The party generally supports "personal liberty" and fiscal conservatism, as compared to the Democratic Party's modern liberalism and progressivism and the Republican Party's social conservatism and right-wing populism. Gary Johnson, the party's presidential nominee in 2012 and 2016, claims that the Libertarian Party is more socially liberal than Democrats, and more fiscally conservative than Republicans. Its fiscal policy positions include lowering taxes and abolishing the Internal Revenue Service (IRS), decreasing the national debt, allowing people to opt out of Social Security, and eliminating the welfare state, in part by utilizing private charities. Its social policy positions include ending the prohibition of illegal drugs, advocating criminal justice reform, supporting same-sex marriage, ending capital punishment, and supporting the right to keep and bear arms.
