We've had our first major upset of the Republican primary!
On Tuesday, there were 3 major events in the Republican primary calendar. Both Minnesota and Colorado held caucuses while Missouri held a non-binding primary. Going into the night, Santorum was expected to win Missouri (he had been campaigning there, while other candidates had been avoiding it) and likely to win Minnesota as well. Colorado, having similar demographics to Nevada (although having a notably smaller Mormon population) was expected to grant Romney a victory. In fact, prior to voting in Colorado, betting site Intrade had Romney at 97% to win the state. To riff off a common sports phrase? That's why they count the votes!
