Six weeks ago, Hillary Clinton won Ohio by ten percentage points. Tuesday night, she won Ohio's equally bitter neighbor to the east by ten percentage points. The voting blocks she relied upon to win the two states are the same: Hillary Clinton was twice carried to victory by white voters, female voters, and voters lacking a college education. Barack Obama made headway with older voters, but saw young voter turnout drop. He also gained among independents, but fewer of them turned out to the polls. Hillary Clinton won Pennsylvania because she successfully defended her base for the six weeks between the Ohio and Texas primaries on March 4 and the PA primary Tuesday.
According to CNN exit polls, women were huge for Clinton in both contests. They were 59 percent of Democratic voters in both Ohio and Pennsylvania, and she won 57 percent of female voters in both contests. White women were particularly important for Clinton. In both states, two-thirds of white women voted for her.
Obama could point to a modest five point jump among white men and four point jump among whites overall. It did not help Obama that the white vote in Pennsylvania was slightly larger than it was in Ohio (80 percent to 76 percent), and the black vote slightly smaller.
In Ohio, those lacking a college education went 58-40 for Clinton. In Pennsylvania, the numbers were a nearly identical 58-42. It's hard to then point to correlations in under $50,000/over $50,000 voting groups (often, voters lacking a college degree and voters making less than $50,000 show identical trends, indicating that they are in fact the same voters), because Clinton won both income groups Pennsylvania, as she did in Ohio. White collar Pennsylvanians were no more receptive to Obama than their blue collar counterparts.
