Potential Factors in the '08 Election
1) Demographic shifts push "purplization" of traditionally red states.
2) Considerable dealignment of Hispanics/Latinos from the Republican Party.
3) New immigrants that should trend increasingly towards Obama (over two million of since 2004).
4) Increased turnout and percentage of African American voters for the Democratic Party.
5) Increasing liberalization and Democratic partisan identification of younger voters.
6) Increasing urbanization and movement towards the coasts.
7) An increase in the amount of early and absentee voters, who have already begun to vote..during an economic crisis that favors Democrats.
8) Higher incidence of reliably Republican military voters voting Democratic?
9) Aging population, mortality of likely McCain voters since 2004 election (perhaps less older, reliably Republican voters than 2004. I theorize this is a problem with having an older base.)
10) Generally high voter turnout.
