Gerrymandered or not, the rural electorate is voting GOP. I'm not sure how much of a difference redistricting would make. Around STL and KC, maybe Dems could pick up some seats, but in the rural areas not sure it'd matter much. Agree that Jeff City treats STL, KC, and Columbia with contempt, even though they generate all the money. MO used to be a decent place to live before the GOP took over.
I think the Missouri GOP, not to be outdone in its MAGA fervor, will actually try to introduce as many diseases as it can in the state while it follows FL's lead to eliminate vaccine mandates. That'll show em!
