Alaska Lt. Gov. Mead Treadwell announced Friday that he was forming an exploratory committee for a 2014 Senate bid.
Though he didn't go as far as to say he is actually committing to a run (he said he was not announcing his candidacy "at this time"), he's the third GOP Senate candidate to either enter a race or form an exploratory committee over the course of a week, joining West Virginia Rep. Shelley Moore Capito and former South Dakota Gov. Mike Rounds.
Alaska Sen. Mark Begich is considered one of the potentially vulnerable Democrats up for reelection in 2014. Treadwell, if he does decide to enter the race, would likely be one of many Republicans vying to take on Begich in red Alaska.
