editor-in-chief Erick Erickson is backing Alaska Lt. Gov. Mead Treadwell's (R) Senate campaign, giving the underdog a potential boost on the right against frontrunner Dan Sullivan (R). 

Erickson, a leading Tea Party voice, writes that Treadwell is "better on the stand your ground law in Alaska than his opponent" and accuses Sullivan of being "'all in on the climate change agenda" because he's voiced support for decreasing U.S. dependence on oil. He also hits Sullivan for having the backing of American Crossroads.

Sullivan has a lead in the polls, more money and endorsements, but it's not just from the GOP establishment. The economically conservative Club for Growth is also backing him, and most view him as the favorite in the race. 

Erickson also makes no mention of the third candidate in the race, 2010 Senate nominee Joe Miller (R), who has a small but fervent Tea Party base in the state.

Sullivan has been mostly ignoring his primary opponents and focusing on Begich.
