Colorado, Minnesota, and Missouri voted tonight. These are beauty contests, with no delegates. Santorum won all three. Missouri was always tipped for him, but Minnesota and especially Colorado were seen as more of surprises. Minnesota, home of Michelle Bachmann and Tim Pawlenty, is no real surprise to me (here's a heartbreaking example of the effects of far right hatred in Bachmann's district - http://www.rollingstone.com/politics/news/one-towns-war-on-gay-teens-20120202 ). Colorado is a surprise, as it has a fairly strong Mormon population and Romney had spent time there.
This basically just reaffirms that many GOP voters do not like Romney and will support him when they have to, but are sending him a message now.
