The State of the Presidential Race after the Philly Debate

Polls show the top issues for voters are the economy, including free trade and $4-a-gallon gas and the war in Iraq.  But less than a week before the Pennsylvania primary, the first 50 minutes of last night's debate between Hillary Clinton and Barack Obama, – the twenty-second in this presidential campaign -- were focused on personal gaffes, past associations and who could withstand a Republican onslaught before the November elections. Eventually, each candidate was forced to concede that the other could beat John McCain.  ABC;s moderators are getting as much post-mortem attention as the candidates. Did anything happen to change the momentum in Pennsylvania?  Are voters around the country better informed? What about the super-delegates who are likely to make the final decision?
