As I'm sure you've heard ad nauseam, there are still 46 45 more states that have yet to weigh in on who should be the Republican nominee for president.

But after Mitt Romney's huge victory in Florida a week ago, the GOP race has gone a bit flat. The inevitability of the former Massachusetts governor looms larger by the moment, despite the fact that he doesn't appear to be all that popular inside his own party.

But lest we forget, there are other candidates besides Newt Gingrich in the race. Like Rick Santorum.

Tuesday night, three states get their moment in the election spotlight: Minnesota, Colorado and Missouri.

The Show-Me State contest is devoid of Gingrich, since he failed to qualify to get on the ballot. And that's leading some analysts to believe that Rick Santorum could possibly steal that state's primary.
