Some more on the Youth Vote and Minorities

The exit polls on the web do break down the vote by age and race. Among blacks, Obama won about the same among all age groups. Among Hispanics, Obama did 8% better among the young than the old, and among whites, Obama did 14% better among the young than the old.

There was an interaction between age and race: many more of the young voters were ethnic minorities. Among blacks and Hispanics, there were three times as many under-30's as over-65's. (By comparison, among whites, there were more old voters than young voters.)

So the age effect partly arose from lots of young ethnic minorities coming out to vote.
