American voters are often misinformed and hold false beliefs about many details of public policy, the size of different portions of the federal government, and who calls the shots in different settings. Nevertheless, political parties should try to be accountable to the people who elected them.
As far as I can tell, the big threat to Trump’s presidency isn’t the Russia investigation or even erratic and irascible Trump himself, it’s Paul Ryan’s legislative agenda. I haven’t seen a single coherent public defense of the AHCA. I think Obamacare was a stupid use of political capital by the Democrats, and “maximizing the percent of the population on comprehensive health insurance” is a stupid political goal (and possibly one with tragic side-effects, as I think I’ve shown.) But the Democrats at least ran on a plan with a passing similarity to what they passed (they more-or-less passed Hillary 2008’s health care plan, since Obama 2008 didn’t have a mandate.) Yes, Republicans over the last several years have won electoral success in part on the backs of “repeal and replace,” but they never made clear what the “replace” was, nor made any kind of public argument for what they put together now.
The Senate should drop the AHCA, pass a small tax cut and a couple minor Obamacare amendments (dropping the employer mandate, for instance), and put a much bigger piece of cash into digging up streets and replacing piping, rebuilding bridges, and building Trump’s wall, which is a clear and fairly popular promise their winning candidate made to his constituents.
