Of the four key Midwest/Rust Belt battlegrounds, we're getting a pretty clear hierarchy where WI and PA are more competitive than MI and MN. You wouldn't go so far as to say Biden doesn't need to worry about MI/MN, but they've become less likely tipping points. https://t.co/iAGM4p2JS8 — PolitiTweet.org
