Assuming this is after Trump's second term:
I don't think JBE would win Louisiana today, but the gradual Democratic trend there combined with him being a (hopefully) popular governor combined with it being a great year for Democrats (after 8 years of Trump) combined with Jeb! being a terrible candidate cause Louisiana to flip. Texas, Louisiana, Arizona, Mississippi, Iowa, Montana, Indiana, and Alaska are decided by incredibly small margins. West Virginia is closer than usual.
