As far as I can tell, those who heard what they wanted in his campaign promises are reasonably satisfied that they are getting it. There's some loss of approval as reality precludes some options, but that happens to everyone. Nor do I think the "apolitical" will become any less so. I see no reason why the midterms should give radically different results. Now, it just so happens that historically things swing a bit back at midterms, and given how close things are that's enough to sway the entire power structure. It's an unfortunate reality of voting: a one-vote margin is no different from unanimity. Even so I do not expect the overall tone to change any time soon. Those proportions seem fairly durable.
