It's just an assessment of the general political outlook. Anyone that thinks the public would tolerate some sort of widespread anti-Trump retribution is living deep in some sort of bubble. Most likely a small, wealthy, liberal one. They literally tried that last time and it resulted in an even more resounding Trump victory than 2016. The majority of the politically active people align with Trump. The old standby of Democrats win when more people vote is no longer true. The majority of the non-voting public aligns much more strongly with current "conservative" values than anything the left is currently offering.
