Barack Obama won Wisconsin's Democratic primary yesterday by 17%--a crushing victory in a state where the Clinton camp was really hoping to stanch the bleeding.
Jay Cost of RealClearPolitics has a fascinating breakdown of the crosstabs, which suggest that Obama's victory was even bigger than it appears at first:
Clinton suffered significant loses across many of her core constituencies. White women, Democrats, union workers, downscale voters, and white Catholics all drifted to Obama last night - some so much that Obama actually won them.
If that pattern continues in Ohio and Texas--and a national poll showing Obama up 14 points suggests the momentum isn't isolated to Wisconsin--this marathon could be over real soon.

GOVERNING Politics is the place for news and analysis on campaigns and elections. If there's a ballot measure in California, a legislative election in Alabama, a mayoral election in Anchorage or a governor's race in Rhode Island, GOVERNING Politics probably is writing about it. We love everything about state and local politics, from polls and campaign ads to policy debates and demographic trends.
