Scott Elliott, over at electionprojection.com has his first major post on Minnesota in the current election cycle. On the Senate race (for Mark Dayton's seat):

The Blogging Caesar originally had this race going ever so slightly to the GOP. However, a major factor in that pick was a primary battle I thought would damage the eventual Democratic nominee. That expectation arose from a mistaken list of Dems in the running. I had previously included two other candidates which are not actually running, and their absence clears the way for Klobuchar to emerge from the primary without much of a battle. So, I'm changing my call on this one. I'm making it a weak Dem hold for Klobuchar.

Check out the rest of the post for a good synopsis of the upcoming situation in Minnesota.
