FWIW....
Polling of Texas by regions of the state, actually show Trump doing well in NorthTex, compared to Houston/EastTex, where his numbers look like he will lose bigley....
I was never able to get a complete breakdown of counties of that Texas poll to look at PVIs, but it is not incompatible to see both a collapse of Republican GE support in suburban and heavily Anglo counties in TX and KS, while also not seeing as big a swing on rural counties of the Great Plains with fewer huge Metro population centers.
It's got to be hard for those areas in rural TX to swing Republican since they're already so heavily Republican to begin with
