MONTGOMERY, Ala. - Just hours after Mitt Romney accused Rick Santorum of being to the left of him, the former Pennsylvania senator hit back, telling the crowd here that his victories show just how conservative he is.

"You have candidates who do not have a conservative record, but who are now - because they are in a primary, they are out there trying to run to the right and say, 'Oh, we're the most conservative,'" Santorum said. "But if you look at the state that just voted on Saturday, Kansas, there's no more rock rib solid conservative state in the country than the state of Kansas, it's about as red as they get. Oklahoma, about as red as they get. And who won Kansas and Oklahoma?"

He told the audience of about 200 at an events center here that if the voters of Alabama and Mississippi, who go to the polls Tuesday, "have any doubt who the true blue conservative is - or the true red conservative is, there is no question."

Earlier today on Fox News, Romney told Neil Cavuto that he "find(s) it interesting that he (Santorum) continues to describe himself as the real conservative" before listing reasons he believes his opponent is not, adding Santorum's "record does not suggest he has the fiscal conservative chops that I have."

He again said if he's the victor Tuesday it will become a "two-person race," suggesting the loss for Newt Gingrich would push him out of the race.

According to several polls, the three candidates are locked in a three-way tie in both states.

The candidate made a final dramatic push for the audience members' votes, telling them their primaries are not usually this important.

"This is the first time your vote in a Republican primary is going to make a difference. And it's going to make a huge difference," Santorum said.

Santorum rallies traditionally go without music - unless it is a primary night party - but this evening the event had more of a campaign rally feel, with a live band named First Love opening up for the candidate. The two girls from Oklahoma have written a song about Santorum called "Game On," after the candidate's famous words when he took the stage after the Iowa caucuses, which later became a victory.
