So who will win the Ohio primary on the Republican side?

FOX's Jeff Monosso reports:

Ohio's the next to vote Tuesday where it could be a do or die contest for two candidates, including Ohio's own governor John Kasich, who had a campaign stop in Youngstown. Told supporters:

(Kasich) "We're gonna be in good shape here, we're gonna win this state and then we're gonna campaign all around the country."

The latest polls show a slim lead for Kasich over frontrunner Donald Trump, who campaigned in North Carolina today on topics like clamping down on illegal immigration:

(Trump) "And we have to be smart and we have to be tough and we have to be less politically correct because that is killing our country."

Ohio is a winner-take-all state and on the Democratic side, Bernie Sanders also hopes for a Michigan style upset over Hillary Clinton, who again leads Sanders here in the polls.
