Emanuel: Obama will win Pennsylvania

Chicago Mayor Rahm Emanuel says Pennsylvania is secure for Obama. Anderson Cooper asked him about Mitt Romney stopping there on Election Day while President Obama made calls and interviews, but did not travel or hold any events. "I think Mitt Romney has to go to Pennsylvania because Ohio is not working the way it has...why is he doing that? The reason isn't just for one more effort. It's because the avenues for an electoral map to victory are not where they were six days ago or six weeks ago. That's why he's trying to look for an opening," says Emanuel.
