College students attending out-of-state schools are not generally known for high turnout numbers

we don't really know; nobody's ever tried to have a caucus so close to the holiday season before. It's a fair bet that the college students from out-of-state wouldn't have had quite have the same kind of interest in the various communities, may not even have been registered to vote in Iowa, and/or thus far hadn't seen the point in turning up in massive numbers for a downtown caucus that only has a fixed number of delegates anyway. I think there's a whole new ballgame here.

(and yes, if they all vote for Obama, I'll be somewhat annoyed, but the main thing is Hillary has really low support amongst this group).
