There is a sad logic to keeping Trump, one I cannot stomach. Consider what he has done for (not to) anti-Republicans such as us. The ACA which is better than the alternatives is still in place although there are problems with lack of proper government management, no rapey tax reform. The military isn't backing his transgender nonsense. Every single time the Republicans might get traction Trump does yet another incredibly stupid thing. He's providing the only counter to the Republicans. It ends in gridlock but without doubt there's worse. The Republicans might have had a productive session.
Ultimately the best we can hope for is to stalemate as long as possible. Who knows? There are signs that some Republicans and Democrats are at least thinking that cooperation might be better than constant stabbing in the back. The trouble there is leadership and the extremists, but it's more than we had.
I'd piss on a spark plug if I thought it would work. I believe that's the quote.
