The Republican numbers among 18-29 year olds are awful.
Contrary to whatever pbrower is spouting, I think this phenomenon may be even worse in Virginia. I can't see these numbers at the moment, but there was a poll that has like 20-25% of them going for Sarvis (L) in the Senate race. May not have been accurate at tge end of the day, but the young may be exceptionally socially liberal there.
Cuccinelli won 18-24 in 2013.
Well, Sarvis voters (15% of the 18-24 & 25-29 vote) + low turnout distorts that.
In 2014, 18-24 voters voted identically to 25-29 voters. Mark Warner also won 18 - 24 voters in 2014.
