Oh hey, election results!
AP has called Minnesota and Missouri (which, just to remind folks, is a totally meaningless popularity contest) for Santorum.
Minnesota (with 82% reporting)
Santorum: 45%
Paul: 27%
Romney: 17%
Gingrich: 11%
Missouri (with 99% reporting)
Santorum: 55%
Romney: 25%
Paul: 12%
Either Gingrich wasn't on the not-really-a-ballot, or he is damn unpopular.
Colorado is still too close to call (53% reporting)
Romney: 39%
Santorum: 35%
Gingrich: 13%
Paul: 13%
This is a surprise. Romney was expected to take Colorado rather handily. He's actually overperforming his poll numbers slightly, but Santorum is way outperforming his poll numbers (in all three states, really). Either his ground game has been much better than people realized, or he's benefitting indirectly from the Romney-Gingrich dustups, as people fall away from Romney but can't stomach Newt and are latching onto Santorum as their fallback option.
I don't see it happening, but if Gingrich were to drop out and endorse Santorum at this point...this could be a nightmare for Romney (and of course, Team Obama would be giddy as schoolchildren on a snow day if Santorum were to win the nomination).
EDIT: Also, props to Team Paul for outperforming in Minnesota. 2nd place finish means we will see no concession speeches from Dr. Paul tonight. And the relentless Bataan Death March to the nomination continues for all four candidates...
DOUBLE-EDIT: One reason that Colorado is still very much up for grabs is that Colorado Springs (home to Focus on the Family and the Air Force Academy, and extremely friendly to evangelical social conservatives) hasn't reported in yet at all. That could be a big chunk of votes for Santorum.
UPDATE: 70% reporting now, and Santorum is within 150 votes of Romney. And still no Colorado Springs. I'm gonna go ahead and say that Santorum makes a clean sweep of all three states. All the remaining counties to report in are rural (where Romney typically fares poorly) with the exception of Colorado Springs, which I think will go hard for Santorum. Losing Colorado is a bigtime embarassment for Team Romney, if I'm right.
