Ken Buck has returned to his tea party roots to reclaim the momentum as he tries to unseat Democratic Sen. Michael Bennet.
After some televised missteps, Buck has resumed the sort of small campaign events where his folksy style first made him a tea party favorite. He defeated a better-funded Republican in the August primary and seemed to have Bennet on the ropes.
Recent polls show the contest's a nail-biter. Bennet and Democrats have succeeded in highlighting Buck's conservatism with a drumbeat of "too extreme" messages. Buck concedes he stumbled during televised debates with Bennet, joking that he can't keep his boot out of his mouth.
