When even TrafLOLgar has Trump losing Wisconsin, it's hard to see how he wins it. It won't be a blowout for Biden, and it would be very close in a less favorable environment for Democrats, but the takes about Wisconsin being a red state and a "heavy lift" for Democrats this year didn't age well.
Who says? The polling average right now Biden +7
Which is actually suggestive of a very slight R trend given his yuge nationwide numbers. I think Xing's point is that Biden is set to carry the Rust Belt trio due to the national environment rather than anything special to do with these particular states. I don't entirely agree with that, but that's my read on what he's saying.
