@nimh,
This was predictable, of course:
More exit poll comparisons, 2000-2004-2008
More side-by-side comparisons of how the exit polls break down the presidential vote by demographic group this year with the numbers from 2004 and 2000 - in simple pie charts. Among which groups has Obama done better, by how much, than Kerry and Gore did? Data on first-time voters, religious groups, married versus unmarried voters, union households and gun-owning households, urban, suburban and rural voters, and voters from the different regions of the country.
