Of course he should still campaign & (potentially) hold rallies in Michigan, but I really hope Michigan's locked in enough to where he can campaign more in Arizona and/or Georgia (Plus some feelers in Texas)
Texas has more to do with turnout and considering the Texas house can flip even with a Democratic PV loss, investment should be made here into registering people to vote here. That will have a huge impact on redistricting. Biden shouldn't necessarily invest a lot of time here though.
I very much agree. I don't care if he puts in all his effort or just a little, I just want him to do something. But to 100% scoff it off, with its basket of close House & state legislative races alone, would be as asinine as rallying in Oklahoma or running ads in DC.
