There's a chance the Electoral College vote could wind up tied, but it's more likely that there will be different electoral and popular vote winners. If either of those scenarios happens, there could be a push to change the way the U.S. elects its presidents.

The effects of the superstorm could hurt turnout in traditionally blue states, limiting the popular vote for President Obama. But if Obama's response to the disaster is looked upon favorably, the opposition might be less motivated to turn out.

Governor Mitt Romney's campaign converted a Dayton, Ohio, campaign stop into a "relief" event for victims of Sandy. But it still bore many of the hallmarks of a traditional campaign event. The Romney campaign was also responding to questions about comments the Republican presidential nominee made last year about partially privatizing and devolving to states certain functions of the Federal Emergency Management Agency.

Stopping the Affordable Care Act may be harder than the law's opponents realize. For one thing, if he's elected, former Massachusetts Gov. Mitt Romney can't just grant waivers letting states ignore the law on his first day as president.

The latest NPR Battleground Poll shows former Massachusetts Gov. Mitt Romney holding the narrowest of leads in the national sample, but trailing President Obama in the dozen states that will decide the election. The poll adds evidence that the Oct. 3 debate between the two men redefined the race.

A new Pew Research Center poll shows that among likely voters, the race is now a statistical dead heat with both President Obama and Mitt Romney receiving 47 percent support. And while Obama holds a slight edge among those registered to vote, a higher percentage of Republicans than Democrats say they actually plan to do so.

At a time when both presidential campaigns would typically be hitting all the swing states, some were off limits owing to Hurricane Sandy. Still, with only a week left before the election, the campaigns both had to find ways to continue their efforts while heeding Hurricane Katrina's lessons.

President Obama urged Americans in Sandy's path Monday to "please listen" to local officials, and his Republican challenger, Mitt Romney, urged help for those affected by the superstorm. The two candidates also canceled campaign events Monday and Tuesday.

Mitt Romney spent years lining up endorsements, donors and state-by-state victory networks. His meticulous strategy paid off in a long GOP primary and has kept him competitive in the general election campaign. It also has revealed glimpses of Romney's loyalty and how he handles mistakes.

Surveys taken in many foreign countries show Barack Obama is widely preferred over Mitt Romney. But in Israel, Romney appears far more popular.
