This also has Trump down 8-14 points. It’s of course early, but I really don’t think Peters will outperform the Democratic nominee significantly, and I wouldn’t be that surprised if James did 1-2% better than Trump (whether that is enough is a different question).
Yes, Peters trailing Trump and being up only mid single digits is not where he needs to be when all Michigan polling in the Trump era has had a 2-4% Dem bias.
That having been said, I don't think MI will be very close in 2020. I expect it will either be all R's win by 5ish or all D's win by 5ish.
