I've argued this for years with regards to third party voting. If you are going to say that most or every Green Party vote that went to Jill Stein should have gone to Clinton, then you have to be willing to say the same of Libertarian Party votes that went to Gary Johnson and say those should be Trump votes on the right. Gary Johnson got 172,136 votes in 2016 in Michigan and Jill Stein got 51,463 votes in 2016 in Michigan. So Johnson hurt Trump more than Stein did Clinton. The numbers get even worse when you factor in the other right wing candidate, Darrell Castle, from the Constitution Party.
These numbers hold in all the swing states as well, Johnson outperformed Stein. So in Pennsylvania and Wisconsin, Johnson took more votes from Trump than Stein took from Clinton.
