If you consider mortality rates it's pretty obvious there were several million 2004 and 2008 voters who died, or were incapacitated over that period of time ~ plus, as we get older, the probability we are going to die climbs, and the Boomers are, to say the least, getting older, so registered Republican boomers died off at a higher rate than the population in general.
Maybe somebody knows an actuarial student who'd like to wrap up a Masters 'splainin' it all in detail.
We need to register more unregistered adults and get them to vote for our guys.
Blacks die at a faster rate than whites at any age ~ so Obama should have lost more voters than the Republicans.
Obama lost more voters than the Republicans!
True on a percentage basis but not with total numbers. Blacks make up about 13% or so of the population, if X% die that is a much smaller number then the same percentage of whites.
