Will it be enough? President Barack Obama holds a 5-point lead on Mitt Romney in Ohio according to a new Quinnipiac University/CBS News poll. The Obama campaign is waging a defensive ground war in the battleground state, which may prove an Electoral College bulwark against Romney’s chances at the White House. But the new numbers are a decline for Obama—while he now leads 50 to 45 percent among likely voters, he held a decidedly stronger lead at the end of September, when he was ahead 53 to 43 percent.
