It's the ninth inning, and the Democrats are bringing their closer to Pennsylvania.

Former President Bill Clinton will make two campaign stops in the Philadelphia area Monday, hoping to boost turnout for President Obama on Tuesday.

Clinton will also appear in Pittsburgh and Scranton, as Democrats work to counter the late push by the Romney campaign to compete in Pennsylvania. As of Saturday morning, the Obama campaign hadn't released details of the Philadelphia area events.

Mitt Romney will speak at a rally in Bucks County tomorrow.

The sudden flurry of campaign activity in Pennsylvania follows two months in which it seemed the GOP had abandoned hope of winning the keystone state. But over the past week, a half dozen Republican groups have bought more than $6 million worth of TV ad time for a late push, and both Romney and running mate Paul Ryan planned appearances in Pennsylvania over the campaign's final weekend.

Ryan is appearing in the Harrisburg area today.

Recent independent polls have showed Romney within four to seven points of President Obama in Pennsylvania.
