Campaign signs for both President Barack Obama, and his challenger, Republican presidential candidate, former Massachusetts Gov. Mitt Romney are seen in yards outside Evans City, Pa., Friday, Nov. 2, 2012. In the final days of the presidential campaign, Romney is making a concerted push into Pennsylvania, aided by outside political groups that are spending millions in last minute ads in the state to help erode Obama's 2008 support. Polling shows Obama holding on to a 4 or 5 percentage point lead over Romney, but the trend has been in Romney's favor. (AP Photo/Keith Srakocic)
