The column labeled "Party 1" corresponds to the political platform of the Democratic Party.

Explanation:

The Democratic Party is one of the two leading parties in America, along with the Republican Party. The Democratic Party draws its origins from the Democratic-Republican Party, founded in 1792 by Thomas Jefferson and James Madison, but the party was formally founded in 1828 by supporters of Andrew Jackson, making it the oldest political party to continue in the world.

When it emerged in the 19th century, it was a conservative party that promoted economic liberalism and pursued the agricultural interests of the slave-owning South. It remained dominant until the Civil War, when many Democrats found themselves on the side of the defeated Confederacy.  

In the 1912 presidential election, Theodore Roosevelt competed as a candidate for the Liberal Progressive Party (he later became a Republican member), eventually leading to the replacement of political platforms between Democrats and Republicans. In 1913, Woodrow Wilson was elected as the first fiscally progressive Democrat president. Since Franklin Roosevelt, the Democratic Party has begun to promote social liberalism and social justice.  

Today, Democrats are largely progressives and centrists and, to a lesser extent, conservatives. The party philosophy of contemporary liberalism advocates social and economic equality combined with the welfare state. The party is committed to state intervention in the economy and increased market regulation. Programs such as union support, affordable tuition, universal health care and equal opportunities for all, consumer protection and environmental protection are at the core of the party's economic policies. The Democratic Party has partnered with smaller liberal regional parties across the United States, such as the Minnesota Farmer Party and the North Dakota Non-Party League.

Long into the 20th century, the party had both conservative pro-business and Southern conservative-populist anti-business wings inside. The New Deal Coalition (1932-1964) received strong support from voters of European descent, many of whom were urban Catholics. After Franklin Roosevelt, the party's pro-business wing was held only among its membership in the states of the South. After the racial turmoil of the 1960s, most Southern Caucasians and many Catholics from the North turned to the Republican Party in the presidential election. After the 1970s, the once significant element of labor unions became smaller and provided less support to the party. Throughout the 1990s, white evangelicals and southerners became inclined toward the conservative Republican Party at the state and local levels at the expense of the increasingly liberal Democratic Party. Racial and ethnic minorities, such as American Jews, Hispanics, Latinos, and African-Americans, tend to support the Democratic Party much more than the Republican, giving the Democratic Party a significant number advantage (80:68).

Fifteen Democrats held the office of President of the United States: the first was President Andrew Jackson (1829 - 1837), while Grover Cleveland served two terms (1885 - 1889 and 1893 - 1897), and is therefore counted as the 22nd and 24th President. The most recent was 44. President Barack Obama (2009 - 2017). Franklin Delano Roosevelt is the only US president to be elected to office four times (1933 - 1945).
