WASHINGTON If President Donald Trump and Republicans make good on their promise to angry rural voters to repeal and replace the Affordable Care Act , those voters may wind up a lot angrier.

And it wont be good for their health or for the electoral prospects of the GOP.

Democrats , at least, certainly think so, and are looking at both fresh polling data and history for evidence that the GOPs repeal and replace effort will also repeal Republican control of Congress.

For Jill Hanauer, who runs the progressive election research and strategy outfit Project New America , the landscape is starting to remind her of Colorado in 2004 , when Democrats did especially well, running in part on a health care message.

The way we really won in Republican-leaning districts of the state legislature was talking about the specifics of health care particularly breast cancer and prostate cancer and other cancer screenings and other prevention, Hanauer recently told The Huffington Post. Thirteen years later, those same issues are, I believe, going to tear this party potentially apart if they dont smell the coffee.

Two things back up Hanauers opinion. One is polling.

A survey her group commissioned with Myers Research delved into Nevada, where Republican Sen. Dean Heller faces a battle for re-election in 2018. First, the poll found Trumps approval ratings are under water, at 42 percent positive versus 50 percent negative. Heller comes out even worse, at just 33 percent favorable and 53 percent unfavorable.

Rebecca Lambe, the senior Democratic strategist widely credited with engineering electoral success in Nevada under former Sen. Harry Reid, said the problem for Heller is that while voters still see Trump as someone they sent to Washington to shake up the system, Heller is part of that system.

Nevada voters will not be giving Dean Heller that same benefit of the doubt they are offering to Trump, as they still see him as part of the problem in Washington, Lambe said.

Hanauer pointed to findings from the survey that suggest voters will give Heller even less love if he helps carry out the repeal bid, especially if the Affordable Care Act, also known as Obamacare, is replaced by the proposal currently moving through the House of Representatives.

Overwhelmingly, Nevada voters are supportive of the specific components of the ACA, with as many as 9-in-10 saying that any replacement should not turn back the clock on coverage and put insurance companies in charge again, the analysis accompanying the polling data says.
