Young voters diverged sharply from the population as a whole, preferring Obama/Biden over McCain/Palin by 66% to 32% in the NEP. This is by far the highest share of the youth vote obtained by any candidate since exit polls began reporting results by age categories in 1976. In past elections from 1976 through 2004, young voters diverged by an average of only 1.8 percentage points from the popular vote as a whole. 2004 had set the previous record for an age gap
A 2 to 1 preference is astounding.
