Mason-Dixon has a Colorado poll out. On the Democratic side, Obama and Clinton are essentially tied, 34-32, with Edwards trailing at 17. In the caucuses, you need at least 15 percent to get any delegates, so Edwards is in an iffy position. Of course, his share of the vote will vary a lot by precinct. On the GOP side, Romney is at 43, McCain at 24, and Huckabee at 17.
I sort of expected a huge Romney lead, given the huge insider advantage he has here. Just about every big GOP officeholder who's endorsed has gone Romney's way. But Clinton has a similar advantage here, and she's only tied in the polls.
