Especially on both coasts. No surprise here.
http://www.slate.com/id/2153272/The exit polls aggregate votes for the House on a broad geographic basis: East, West, Midwest, and South. Yesterday, the poll for the House vote in the East showed that the 25 percent of the electorate making over $100,000 went big for Democrats overall, 57-42, compared with a 49-48 margin in 2004. In 2006, those making between $150,000 and $200,000 voted for Democratic candidates by a whopping 63-37 majority, and those making more than $200,000 went Democratic by a slim 50-48 margin. That's a huge shift from 2004, when Republicans took the $150,000 to $200,000 demographic 50-48 and rang up a huge victory among the over $200,000 set: 56-40. In 2006, Democratic candidates racked up big wins among college graduates—63-35, compared with 55-42 in 2004—and among those with postgraduate degrees—68-31, compared with 58-38 in 2004.
A similar dynamic could be seen in the House vote in the West, where Democrats won the high-income demographics by smaller majorities: 53-45 in the $100,000 to $150,000 slice; 50-46 in the $150,000 to $200,000 segment, and 52-48 in the over $200,000 category. Again, that represents a big shift from 2004, when Republicans won the $100,000 to $150,000 group 51-48 and took the over $200,000 group 54-46. In 2006, Democratic candidates increased their margins in the West among college graduates and those with post-graduate degrees—anthropologists at Berkeley, yes, but also MBAs, lawyers, and doctors.
