And while it looks like Romney and Santorum will continue sparring for a while longer, Newt Gingrich and Texas Rep. Ron Paul aren't showing signs of leaving the show anytime soon.

Although Rick Santorum soared to victory in three primary elections on Super Tuesday, the general consensus is that this is Mitt Romney's game, even if the Republican base is divided on his merits.
Romney, the one-time governor of Massachusetts, scored a home-state victory and five others on Tuesday, although his win in Ohio was narrow, highlighting his problem appealing to the Republican base as a whole.
"If Romney would have won decisively, it would have brought this closer to him becoming the eventual Republican nominee to take on President Obama," said John Baick, a professor of history and political science at Western New England University. "Romney seems to have outspent Santorum 10-1 in Ohio, so the fact that Santorum came so close is amazing. At the same time, Santorum wouldn't have gotten this far if Romney wasn't the front-runner. He rises mostly because of the lack of enthusiasm for Romney."
Romney has a few options when it comes to shoring up support with Republicans across the country, but they all involve avoiding future gaffes, particularly those which emphasize his wealth.
Baick noted that over the past few weeks, Romney's appearances are more scripted, thus limiting the chance of such a mistake being spoke. But in order to have a realistic chance of defeating Obama, he is going to have to go further.
"He is going to have to pick a vice president that satisfies the doubts people in the party are holding right now," Baick said. "Possibly a southerner, someone with impeccable religious credentials to appeal to the evangelical part of the party."
That eliminates Sen. Marco Rubio, R-Fla., Baick said. Although Rubio is Catholic, he was once a Morman, and that isn't solid enough for many hardcore Christians, particularly along the Bible Belt of the South.

A Los Angles Times article published Tuesday from Alabama highlights Romney's problem appealing to such voters and also showcases the rural-urban divide.
One man, a lifelong barber, told the LA Times that his problem with Romney is the fact that he is a Mormon.
"Christ is the head of my church, and his was some Smith guy who claimed to be a latter-day prophet," the man told the LA Times.
Another person said that he would support Romney against Obama, but he sees Romney as being cocky.
"In the contest until now, the rural urban divide has been negligible," said Matt Barron, a political analyst not working with any of the presidential campaigns. "But in Ohio on Tuesday, Santorum hammered Romney, taking much of the rural vote in part because of his appeal to Christian evangelicals. The same thing happened in Tennessee, which Santorum ended up winning."
In Ohio, Santorum took 42 percent of the rural vote, compared to Romeny's 30 percent. The overall state-wide vote broke down with Romney taking 38 percent of the vote, compared to Santorum's 37 percent.
"Romney has an organized political machine and Santorum doesn't," Baick said. "But the only way Romney could finish this race before the Republican National Convention is if he runs the table. And with Santorum's unexpected momentum, he isn't going to do that."
And while it looks like Romney and Santorum will continue sparring for a while longer, Newt Gingrich and Texas Rep. Ron Paul aren't showing signs of leaving the show anytime soon.
Baick said that he believes Gingrich, who won his home state of Georgia on Tuesday, will stick around to enjoy the political platform the race allows.
"Gingrich isn't thinking about 2016 like Santorum, he just wants to be seen and heard and he has this platform to speak his views right now," Baick said. "He could help shape the race by dropping out and endorsing Santorum wholeheartedly, but that isn't likely at this point."
The survival of Gingrich's campaign relies largely on the continued financial support from Sheldon Adelson, a Las Vegas casino owner who befriended Gingrich when he served as speaker of the house in the 1990s. Adelson has spent millions supporting Gingrich's run and continues to do so today.

And Paul, who has a dedicated support base, has no reason to stop, ever, according to Baick.
"Ron Paul has what the other Republican candidates wish they had- true believers," Baick said. "Paul's supporters believe in the man and his message. They see him as sincere. Romney is considered by many as a means to an end. But Paul will always be revered, even when he dies."
A Republican candidate must have 1,144 delegates at the national convention to win the party's nomination. After Super Tuesday, Romney has 415 delegates, followed by Santorum with 176, Gingrich with 105 and Paul with 47.
Looking forward, voters in Kansas will hit the polls for their caucus on Saturday with primary elections scheduled for Tuesday in Alabama, Mississippi and Hawaii.
