North Carolina State Sen. Phil Berger (R), the pro tempore president of the Senate, has been weighing a challenge to United States Sen. Kay Hagan (D-NC) but hasn't officially made any decision yet -- but several things signal that he's ready to jump in the race. The Washington Post asked earlier this month if Berger was positioning himself for a senate run after he announced a $100,000-plus ad campaign that touted the state's new voter ID legislation.
