The Hill: The margin separating Sen. Michael Bennet (D-Colo.) and Republican Ken Buck in Colorado's Senate race was smaller than 9,500 votes Wednesday morning. With 79 percent of precincts reporting results, Buck was clinging to a slim lead in a race that could be headed for a recount unless the Republican prosecutor pulls away - a scenario that seems unlikely, given that plenty of the vote is still outstanding in Boulder County, a Democratic stronghold. Neither candidate declared victory Tuesday, with both sides expressing confidence that votes still outstanding would break their way.
