The Jefferson County Republican Party is demanding Congress immediately repeal the Affordable Care Act or, if it can't, to elect new congressional leadership.

A strongly worded resolution adopted unanimously by the county party's executive committee earlier this week maintains that the failure of congressional Republicans to overturn the sweeping health care legislation known as Obamacare "has caused great consternation and angst among registered Republicans in Jefferson County" and put GOP candidates "in great election peril."

The county party is giving Congress until Nov. 1 to "repeal the abominable legislation," but if Republicans "fail to meet our demand ... and continue in their deceit of the voters," the Jefferson County GOP want different Republicans in charge of the House and Senate.

GOP efforts to repeal Obamacare fell one vote short in the Senate at the end of July when Arizona Sen. John McCain joined fellow Republican senators Susan Collins of Maine and Lisa Murkowski of Alaska voting against a so-called slimmed-down repeal measure. The Republican-controlled House approved legislation to repeal and replace the Affordable Care Act in May, but the hurdle is higher in the Senate, where Republicans hold a 52-48 majority.

"People are blaming three senators," Joe Webb, the Jefferson County Republican chairman since February, told Colorado Politics. "But the failure of the three senators is a failure of leadership, and we're saying if leadership can't get it done, get new leadership."

That means ousting House Speaker Paul Ryan and Mitch McConnell, among others, he said.

"It is imperative that we differentiate ourselves from the National GOP," the county party wrote on Facebook Tuesday. "Otherwise, our local and state candidates will be painted with the same brush as the GOP in Washington. Those in Washington are not doing what they promised, and we intend to hold their feet to the fire."

Jefferson County is Colorado's fourth-most populous county and is often listed among the country's bellwether counties, although it's voted for Democrats at the top of the ticket in the last five cycles - Barack Obama and U.S. Sen. Michael Bennet twice and Hillary Clinton and former U.S. Sen. Mark Udall once. The county has an almost equal number of registered Democrats and Republicans, but unaffiliated voters have a plurality.
