In Colorado Mitt Romney looks primed for another big Western win to match his one in Nevada. He leads with 40% there to 26% for Rick Santorum, 18% for Gingrich, and 12% for Ron Paul.
Minnesota looks like a toss up with any of the four candidates having some shot at winning. Santorum holds a small edge there with 29% to 27% for Romney, 22% for Gingrich, and 19% for Paul.
What both states have in common is that Gingrich has fallen precipitously since our last polls in them. In Colorado Gingrich was in first place with a 19 point lead in early December. His support has declined 19 points since then and his net favorability has dropped 33 points from +41 (64/23) to only +8 (49/41). Gingrich has had a similarly large decline in Minnesota, but there it's much more abrupt. We polled the state only two weeks ago but in that time he's dropped 14 points from 36% to 22%, and his favorability has 26 points from +34 (59/25) to +8 (47/39). That after glow from South Carolina has worn off real fast.
Tuesday has the potential to be a big day for Rick Santorum. In addition to these two polls, a Missouri survey we conducted last weekend found him with 45% to 34% for Romney and 13% for Paul. Given how quickly things have moved in this race I wouldn't assume Santorum still has that lead, especially given the momentum Romney has after big wins in Florida and Nevada. But nevertheless it looks like Santorum has a decent chance at wins in Minnesota and Missouri, and a second place finish in Colorado. 72 hours from now he may have supplanted Gingrich as the top alternative to Romney.
