at transforming his agenda into reality. The thing is that many of his changes are destructive and will be irreversible. It's much more difficult to construct new legislation than it is to take it apart: the ACA comes to mind as well as Trump selling off public lands, or removing federal funding from PBS. Once they are gone, it will be difficult to recreate them, because legislation that creates something new usually requires 60 votes in the Senate-- the great wall of Trump being the exception that proves the rule.

beyond his obvious unpresidential qualities was the rubber stamping of the conservative agenda the GOP had planned-- especially against the safety net-- Medicare etc. The GOP had made very clear what they were planning. So few ads really emphasized this idea (some did), even though elected Democrats knew what could come if Trump won. Even Democratic Senate and House candidates probably did not publicize this enough as perhaps the key reason to reduce rather than add to GOP power. But the public, outside of politically active partisans, basically had very little idea what was coming-- and now they are in for a surprise.
