Obama Closes to Within 5 Points of Clinton in Pennsylvania

Rasmussen's latest survey of likely voters in Pennsylvania shows Clinton struggling to hold on to her lead. While Clinton entered March with a 15 point lead, Obama has closed the gap to 5 with 11 percent still undecided. Sen. Bob Casey's endorsement was undoubtedly significant, as was Clinton's ficticious tale of landing in Bosnia under sniper fire. The poll had a sample size of 730 and margin of error of +-4.

To win Pennsylvania, Obama will need to make inroads into a sixteen-point Clinton lead on the economy while expanding his own seventeen-point lead on the war in Iraq. So far, so good.
