Huffpo's Mayhill Fowler has more from Obama's remarks at a San Francisco fundraiser Sunday, and they include an attempt to explain the resentment in small-town Pennsylvania that won't be appreciated by some of the people whose votes Obama's seeking:

You go into these small towns in Pennsylvania and, like a lot of small towns in the Midwest, the jobs have been gone now for 25 years and nothing's replaced them. And they fell through the Clinton administration, and the Bush administration, and each successive administration has said that somehow these communities are gonna regenerate and they have not.

And it's not surprising then they get bitter, they cling to guns or religion or antipathy toward people who aren't like them or anti-immigrant sentiment or anti-trade sentiment as a way to explain their frustrations.
