First lady Michelle Obama spoke to hundreds of supporters and volunteers at a ticketed event at the National Constitution Center in Old City on Wednesday afternoon.
She touted achievements such as the health care act, employment gains and tax cuts. She says the November election could come down to just a few voters registered by supporters.
President Barack Obama handily won Pennsylvania in 2008 against Republican John McCain, and the state has supported Democrats in the most recent five presidential elections. This year, Republican candidate Mitt Romney is pushing to take the state away from Obama.
