"So we have another poll with Trump doing better with those in the $50-100k income range than he does with those over $100k."
Surely this does not shock you, correct? It totally tracks the CW.
Trump has always done better with middle class voters - it's been his base.
There have definitely been *some* polls that have him doing best with the wealthiest income group, but most of them seem to have him doing best with the middle. But I haven't systematically looked at every single poll to track this. I'll be interested to see what the national exit poll looks like on this question.
