Indigenous peoples of the Americas

The indigenous peoples of the Americas are the pre-Columbian inhabitants of the Americas, their descendants, and many ethnic groups who identify with those peoples. They are often also referred to as Native Americans, First Nations and by Christopher Columbus' historical mistake Indians, modernly disambiguated as the American Indian race, American Indians, Amerindians, Amerinds, or Red Indians.

According to the still-debated New World migration model, a migration of humans from Eurasia to the Americas took place via Beringia, a land bridge which formerly connected the two continents across what is now the Bering Strait. The minimum time depth by which this migration had taken place is confirmed at c. 12,000 years ago, with the upper bound (or earliest period) remaining a matter of some unresolved contention. These early Paleoamericans soon spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes. According to the oral histories of many of the indigenous peoples of the Americas, they have been living there since their genesis, described by a wide range of traditional creation accounts.

United States Politics

Politics in the United States have operated under a two-party system for virtually all of the country's history. For elective offices at all levels, state-administered primary elections are held to choose the major party nominees for subsequent general elections. Since the general election of 1856, the two dominant parties have been the Democratic Party, founded in 1824 (though its roots trace back to 1792), and the Republican Party, founded in 1854. Since the Civil War, only one third-party presidential candidate—former president Theodore Roosevelt, running as a Progressive in 1912—has won as much as 20% of the popular vote.

Within American political culture, the Republican Party is considered "center-right" or conservative and the Democratic Party is considered "center-left" or liberal. The states of the Northeast and West Coast and some of the Great Lakes states, known as "blue states" in political parlance, are relatively liberal-leaning. The "red states" of the South and the Rocky Mountains lean conservative. The current political culture is highly polarized.

The incumbent president, Republican George W. Bush, is the 43rd president in the country's history. All U.S. presidents to date have been white men. If Democrat Barack Obama wins the forthcoming presidential election, he will become the first African American president; if Republican John McCain wins, he will become the oldest man ever to ascend to the office, and his running mate, Sarah Palin, will become the first female vice president. Following the 2006 midterm elections, the Democratic Party controls both the House and the Senate. Every member of the U.S. Congress is a Democrat or a Republican except two independent members of the Senate—one (Joe Lieberman) a former Democratic incumbent, the other (Bernard Sanders) a self-described socialist. An overwhelming majority of state and local officials are also either Democrats or Republicans.
