COLUMBUS -- A new poll shows businessman Herman Cain rising to the top of the Republican presidential field among GOP voters in the battleground state of Ohio.
A Quinnipiac University poll released Wednesday shows the former Godfather's Pizza executive favored by 28 percent of Ohio Republican voters. Cain was in the single digits in a similar survey last month.
Former Massachusetts Gov. Mitt Romney is second with 23 percent.
Both Cain and Romney have visited Ohio in recent weeks.
The poll has Texas Gov. Rick Perry trailing Texas congressman Ron Paul and former U.S. House Speaker Newt Gingrich.
President Barack Obama still leads his potential GOP challengers, though most voters disapprove of the job he's doing.
The poll of 1,668 registered voters has a margin of error of 2.4 percentage points.
