First off, Alaska has been clearly leaning the Republicans' way for some time now as Dan Sullivan (R) has consolidated much of the GOP base following the primary and Sen. Mark Begich's (D) numbers have fallen to around 41%. Begich has made a couple of mistakes of late after previously running an admirable campaign in one of the nation's reddest states. I probably should have changed this rating sooner, but it's time for the rating to reflect the true state of the race, which is about as competitive as New Hampshire or North Carolina (perhaps a bit more so due to notorious polling inaccuracies in the state). This represents the seventh pickup for Republicans.
AK - Begich: Leans R
Second, in Colorado, Cory Gardner's run a smart campaign, approaching the race as a blue state Republican in the mold of Scott Brown or Mark Kirk. A skillful campaigner and reliable conservative, Gardner could end up with presidential ambitions if he wins this seat. However, liberal incumbent Mark Udall benefits from changing demographics and the fact that Colorado has all-mail balloting. Gardner has the momentum as of now, leading in three straight polls, and although Sabato is skeptical of Gardner's ability to translate a slim Election Day advantage into a victory over the incumbent, Nate Silver lists the young congressman as a small favorite.
I'm really uncomfortable about counting out either candidate in this race, but I'm going to go with Gardner in this one due to the president's unpopularity, the GOP's slim lead in the generic ballot which I expect to grow or stay the same, the fact that Michael Bennet barely fended off a far weaker challenger in 2010, and the fact that Udall remains stuck around the president's approval clip while Gardner is surging. I feel crazy making a call on this election at all, but I've got to make sure a call's made by Election Day. This represents the eighth GOP pick-up.
CO - Udall: Leans R
Nigerian Kenya and all others who have offered their predictions, I have enjoyed prognosticating on this set of races together, and hopefully I'm back on by the big day, but if not, the best of luck to you all. Regardless, even if I do come back, this will probably be my last involvement in the General forum, so look for me in the NSG Senate RP if/when it restarts.
