oopsie, Obama actually won by a larger margin among postgraduates according to exit polls. I had included a link to a poll done before the election. After the election it turns out that Obama got the postgraduate vote by 18 percentage points.
Postgraduates continued their steady march -- professionals toward the Democratic Party. One of the sort of stylized facts about American politics in the last 30 or 40 years is the realignment of professionals from Republican to Democratic, and that just continued in this election -- going up. At least it's the best proxy we have in the exit polls for it -- 58-40 Obama among postgraduates. http://www.nationaljournal.com/njonline/no_20081121_5046.php
6. The march of professionals toward the Democratic party continued. Using those with a postgraduate education as a proxy for this group (the exit polls have no occupation question), Obama received 58-40 support. That figure includes 54-44 support among white postgraduates. http://takingnote.tcf.org/2008/11/digging-into-th.html
Dew, another interesting thing to note is that the one state in the top 10 that did vote for McCain (Montana) only gave him a 2.5 percentage point lead over Obama. To my way of thinking, that's not all that much.
A moment after I put this on the board, I realized I'd made a mistake, but figured that I'd see if anyone would correct me on it. No one did, so I guess that I'll fix it myself.
Seven of the bottom 10 states voted for McCain.
I counted #40 (Georgia) in the bottom 10, when Georgia actually just eeks by.
