Blacks staying at home is no problemo for Paxton (and might help with the re-drawn House districts in several places). The bigger question is going to be the hispanic trend lines state-wide. In the primary vs. Cornyn, he got around 52-55% I think. Trump won 55% state-wide in 2024 of those voters vs. Kamala, but I could see Paxton in the mid to low 40's, which will inevitably become the talking point for Dems if so.
