6:05 p.m. ET - Sixty-two percent of Ohio voters said they will "definitely" vote for the Republican nominee, whoever it is, while 23% said they probably would and 10% said only if their candidate of choice captures the nomination, according to CNN exit polling.

6:02 p.m. ET - When asked about their expectations for Tuesday, Team Romney told @crowleyCNN "We just want to get more votes than the other guys."

"State wins get the headlines, delegates win the nomination ... at the particular level we count the later," Romney sources told CNN. "In the end, we want both and think we'll do well."

Going forward they said the campaign will focus on Missouri and Illinois but there will be "no change in strategy or message."

Are they worried about independents deserting the Republican Party because of the nasty race?

"As far as the primary, the long calendar is just part of the process. We are only campaign that can withstand the drawn out primary schecule. Bruises may take time to heal, but they will."

5:40 p.m. ET - @jimacostacnn reported that senior Santorum strategist Hogan Gidley called the case made by the Romney campaign that Santorum cannot mathematically reach the delegates necessary to secure the nomination "not compelling."

"He’s got to get to 1144 too. It’s not compelling," Gidley told reporters in Stubenville, Ohio. "He wants us out because he can’t get there. And if we all go to the convention with a certain amount of delegates and we have to figure something out at the convention so be it but that’s democracy and that’s how the party structure is set up. And we’ll cross that bridge when we get to it."

When told that was the argument then-Sen. Barack Obama made about then-Sen. Hillary Clinton during the Democratic primary contest in 2008, Gidley said: "It’s another issue where Mitt Romney lines up perfectly with President Obama. First it was the issues. Now it’s campaign strategy. You gotta love it."
