The Democratic Party is one of two major contemporary political parties in the United States. Founded in 1828, it was predominantly built by Martin Van Buren, who assembled politicians in every state behind war hero Andrew Jackson, making it the world's oldest active political party. Its main political rival has been the Republican Party since the 1850s, with both parties being big tents of competing and often opposing viewpoints. Modern American liberalism — a variant of social liberalism — is the party's majority ideology. The party also has notable centrist, social democratic, and left-libertarian factions.

John Hayden Lynch is an American attorney, businessman, and politician who served as the 80th governor of New Hampshire from 2005 to 2013.

Lynch won re-election in landslide victories in 2006 and 2008, and comfortably won a fourth term in 2010.

The Republican Party, also referred to as the GOP, is one of the two major contemporary political parties in the United States. The GOP was founded in 1854 by anti-slavery activists who opposed the Kansas–Nebraska Act, which allowed for the potential expansion of chattel slavery into the western territories. It has been the main political rival of the Democratic Party since the mid-1850s. Like them, the Republican Party is a big tent of competing and often opposing ideologies. Presently, the Republican Party contains prominent conservative, centrist, populist, and right-libertarian factions.

In political science, voter turnout is the participation rate of a given election. This is typically either the percentage of registered voters, eligible voters, or all voting-age people. According to Stanford University political scientists Adam Bonica and Michael McFaul, there is a consensus among political scientists that "democracies perform better when more people vote."
