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.

David Gergen says President Obama has an edge going into Election Day because of the way he handled Superstorm Sandy. "That means he's favored, but Romney can still pull off this upset. It is so very much within his power. He's got a lot of enthusiasm on the ground," says Gergen.

On Election Day, Mitt Romney will campaign in Ohio and Pennsylvania. Anderson Cooper asked Candy Crowley why the Republican candidate would spend time trying to convince voters in a state that hasn't supported a GOP ticket since 1988. "First of all, it's right next door to Ohio so it's not like they have to go across the country to go there. Plus, more than 90% of Pennsylvanians will vote on Election Day. There's no early voting in pennsylvania," says Crowley about the campaign's strategy.

Paul Begala says it's almost impossible for Mitt Romney to get 270 electoral votes without winning Ohio. Ari Fleischer disagrees with that assessment and presents a different version of how Romney could win, prompting Begala to respond, "If my aunt had a moustache, we'd call her my uncle."

CNN's Jeffrey Toobin says both presidential campaigns have thousands of lawyers ready for potential legal battles. The first lawsuits have already been filed in Ohio over how provisional ballots will be counted, and in Florida over the deadline for early voting.

David Gergen explains why historically Democrats have an advantage because states they typically win have more electoral votes. "The last five elections, there are 19 states that have gone Democratic in five straight elections. They amount to 243 electoral votes. There are 22 states that have gone Republican, but there are only 180 electoral votes," says Gergen.

Van Jones believes if the youth vote shrinks from 18% in 2008, Pres. Obama will be in trouble. "Who votes will tell us a lot about who will win," says John King about the voter demographic, which could determine the outcome if there are slight changes from what's expected.
