From the Nation, a very nice chart showing how Obama fared in his rough journey across the Rust Belt from March to May.
On the one hand, the chart shows stability -- he's not going from behind to ahead among tough demographics. So it's the makeup of states that has a larger effect on outcomes. But on the other, it shows fairly steady progress from Ohio -- his share of all the slices is going up, not down. It's a counter to the Clinton electability argument:
"In Indiana, Obama improved his support across several key demographics, despite a bruising month of attacks on his pastor, patriotism and populism. Compared to Ohio and Pennsylvania, he generally drew more votes from white women, Catholics, gun owners, households earning under $50,000 annually, voters prioritizing the economy, and voters without a college degree."
