Ambinder passes along some new data:
It's taken about a year, but thanks to new Census numbers and to Project Vote, we now have the most accurate picture of who voted, who didn't vote, and how the voting patterns compare to previous elections. The highlights: 64% of the 204 million voting-age Americans voted, up about 6 million in number and 4 percentage points from 2004. Historically underrepresented groups made gains in this election. Non-whites made up more than 90% of the increase in the total number of voters. The authors conclude that had non-whites voted at the same percentage as whites, more than 5 million more votes would have been cast in 2008. The study, by Douglas Hess and Jody Herman, finds that had voters under 30 voted at the same rates as their counterparts over 30, more than 7 million additional ballots would have been cast.No wonder Republicans worry about a Democratic demographic storm.
