New maps: Democratic primary results as of April 5

Taking into account updated results from several primary and caucus states, here is a county-by-county map on the relative strengths of Barack Obama and Hillary Clinton so far. (Look for a separate post with county-by-county spreadsheets for the real geeks.) First, the differences between the two candidates measured by percentages of the vote. If the big map isn’t detailed enough, click on one of the thumbnails below for regional close-ups.

Next is a map showing the difference in raw votes between the two candidates.


Of particular interest is Ohio, where Clinton won a solid victory over Obama in March. Obama got big vote advantages in Cleveland, Columbus, and Cincinnati, but Clinton countered with big hauls in Akron and Youngstown, in the northeast. Coupled with her wins in most of the rural counties, this was enough for a 10-point edge statewide. This outcome was in stark contrast to Obama’s win in Missouri, Georgia, Maryland, and Virginia, where he won the major cities and didn’t have to worry about mid-sized, industrial, overwhelmingly white areas like Youngstown.

Wisconsin is the one major state where Obama did well in mid-sized cities without a lot of minority voters. (His biggest margins came from the major city of Milwaukee and the university town of Madison, but Clinton failed to compensate with significant wins in places like Kenosha, Racine, and Green Bay.) Can he get put that coalition back together in Pennsylvania?
