Following up on PPP's brutal Obama poll numbers yesterday, Josh Kraushaar at the National Journal sees a troubling trend for the president's reelection chances in Pa:

And the White House can’t be too optimistic when looking at Obama’s standing in the key battleground states.  Obama’s approval rating is at 42 percent in Pennsylvania, according to a new Public Policy Polling (D) survey. His favorability rating in the Keystone State was even lower, at 41 percent, in a separate mid-March Franklin and Marshall poll.  It’s a Democratic-leaning state, but one filled with blue-collar voters and seniors.  Winning re-election without Pennsylvania’s 20 electoral votes would be difficult.
