WI is lean R

Exactly for Warren and Buttigieg, but it's lean D for Biden and tilt D for Sanders.  And either Uncle Joe or Bernie is going to be the nominee.

It's lean R against all dems. He is within the MOE in all of these polls and polls notoriously undercount his support.

This is primarily due to improper weighting by the pollsters in 2016.  Do you think pollsters never learn or adjust their models?  For some pollsters this might be true, but not for the good ones (of which Marquette is certainly one).  Just because this happened in 2016 does not mean it's guaranteed to happen in 2020; you're making the same mistake that Democrats did by assuming that what was true in 2012 would also be true in 2016.

Trump being underestimated in 2016 doesn't mean he will be in 2020. Turnout patterns, the strength of a campaigns GOTV operation and polling methodology change each election and are all responsible for systematic polling errors. If you don't believe me just look at the difference from 2012 to 2016 where state polls went from underestimating Obama to overestimating Clinton 4 years later or how UK polls underestimated the Tories lead in 2015 and 2019 while overestimating it in 2017.
