Santorum lowers Super Tuesday expectations

Republican presidential hopeful Rick Santorum set out on Sunday to moderate expectations for his performance in Ohio and other super Tuesday contests, despite the state's electorate that appears to be designed for his candidacy.

"It’s a tough state for us, only because of the fact of the money disadvantage," Santorum said on "Fox News Sunday." "We’re running a grassroots campaign we’re hanging in there, and we're going to do very, very well."

"We have the anti-Romney vote, if you will," he said.

Santorum insisted that the Ohio primary would be an uphill battle, despite the state's blue collar, rural and evangelical populations.

Santorum could also be ineligible for up to 18 of the state's 63 delegates at stake on Tuesday. And he did not submit enough signatures to land him on the Virginia primary ballot.

Nonetheless, the former Pennsylvania senator said he's putting his fate in the hands of states like Tennessee, Oklahoma, Ohio and North Dakota.

"We’ve done amazingly well for a campaign that early on didn't have a lot of resources and we’ve gotten on a lot of ballots," he said.
