In an interview with America's Newsroom co-host Bill Hemmer, House Speaker John Boehner (R-0hio) guaranteed that Mitt Romney will win Ohio tomorrow.

"There's no question in my mind that we will win Ohio," said Boehner, after being asked

whether he would be willing to guarantee that the Buckeye State's 18 electoral votes will go to Mitt Romney.

Many political analysts believe the winner of Ohio will come out on top in a closely contested election.

Boehner explained

that the Romney campaign has the enthusiasm on its side in his state and he thinks the Romney ground game is "bigger and more sophisticated than anything I've seen."

Watch that clip, here.

The discussion moved on to Boehner's relationship with Romney, his thoughts on what kind of president Gov. Romney would be, and the GOP's prospects in tomorrow's House races.

Boehner also pointed out that the task facing Romney tomorrow is extremely difficult.

"Defeating an incumbent president is an overwhelming job - just ask John Kerry. It's really hard to do," he said.
