How Early Voting Changed the Game in 2008
Michael McDonald’s great early voting website has the totals.

31,268,357 voters have cast votes early in America, which represents 25.3% of the total of all ballots cast in 2004. Nobody doubts we are headed for an absolute record turnout in this election.

22.5% of Americans cast their vote early in 2004, and if that number held true for this election, then 138,970,474 Americans will end up casting ballots.
