At this stage I am tempted to use 100-DIS as the ceiling for Trump support. Thus if Trump has a disapproval of 57% in Michigan, he cannot get more than 43% of the vote -- roughly -- in Michigan in a re-election bid.
One might be tempted to adjust that number upward to adjust for Trump supporters being more likely to go to the polls... but it is too early to do that. At this stage, disapproval is far more difficult to dislodge than is approval. I hear very few people defending him even in a rural area in which he won about 65-35. I noticed that at a harvest festival in town the Republicans had a booth -- and no Trump material. It was as if the Republicans had some question of who would be their standard-bearer. Maybe they were afraid of people giving stiff-arm salutes or shouting "Heil Trump!" in mockery. I think they are beginning to recognize that Donald Trump was a mistake.
You always vomit hate, you and pittsburgh steel do not even see the reality
