As much as anything, Trump is a symptom of the long-term corruption and degradation of the Republican Party. A healthy party would never have been in a position to have been taken over by him.

And even the takeover is exaggerated. Republicans are putting up with him for now because he's going along with their wealthiest funders' goals. What does Trump know or care about health care anyway? Less than nothing, but he's a useful, if unreliable, puppet... for now.
