Preliminary results from the 10 Regions of American Politics are below, with more detailed data to come. Barack Obama has won six regions, taking South Coast away from the Republican column. That means he's won the five most urbanized regions (see earlier post), four of them by margins near or above 20 points, plus he hung on to the Democratic Party's last remaining region with a substantial number of "small town" voters (Chippewa).
The shift of Mega-Chicago and El Norte, which are now almost as Democratic as the Northeast Corridor and Upper Coasts, is significant. Mega-Chicago voted for Gerald Ford in 1976 and George H.W. Bush in 1988, and El Norte was one of Ronald Reagan's strongest regions in the 1980s. The GOP can't afford wipeouts in all four regions if it is to be competitive in 2012.
