Republican presidential nominee Mitt Romney told a northern Ohio crowd he might be defeated by President Barack Obama in Tuesday's presidential contest, but it's doubtful.
Supporters booed when Romney speculated on the consequences of an Obama second term. He then responded that it's possible, but not likely the president will win.
A poll released by the Columbus Dispatch on Sunday indicated Obama led Romney in Ohio 50 percent to 48 percent. That was within the poll's 2.2 percent margin of error.
Romney made a specific plea to independent and undecided voters in Cleveland. He was campaigning in three other battleground states on Sunday - Iowa, Pennsylvania and Virginia.
He is expected to appear in Columbus on Monday. The campaign event at Landmark Aviation at Port Columbus International Airport is scheduled to begin at 6 p.m.
