Dems will never nominate someone whom is a lightning rod like Hilary or Debbie Wasserman-schultz or AOC that would lose WI, MI or PA, again.
This is assuming that any of those states are necessary for the Dems' path to the White House in the future. They may be (sorta) now, but that's not necessarily the case in 20, 30 years, etc. Just like OH isn't really part of the Dems' path anymore.
Anyways, the answer to the question is no, at least given their current demographics, but that probably doesn't matter so much to the Dems. Their future coalition is not going to be particularly dependent on the Rust Belt. That is, unless the parties completely reverse their current trends.
