I wouldn't be surprised by solid D victories in these states. Trump's approvals have been in the toilet in WI, MI and PA since like four months into his Presidency and these states all gave Democrats resounding victories in 2018.
Add on top of this that Trump won these states by less than a percent and it increasingly looks difficult for Trump to win them again. Of course a 2016 redux where both candidates end up covered in mud and enough people say "to hell with it" and vote for Trump again is possible but it's probably much less likely than we all think.
Our reliance on the polls last time proved to be a massive disappointment and presented inaccuracies. Michigan definitely won't be voting for another TPP globalist.
People who do this sh**t are so annoying. "Polls were wrong once, therefore we can never trust polls again," without any understanding of why polling was wrong and whether and how that applies to current races. It's such lazy analysis.
