Has to be fairly recent with Jefferson going D. It’s either 2008, 2016, or 2020, since Obama won a few more in 2012.
I really want to say 1980 but South Texas is making me doubt that.
Maybe
1928 then - South Texas should be solidly Democratic in all elections but 2020 (obviously not 2020 given the results in all the other counties) and 1972 (obviously not 1972 because McGovern won like 5 counties in TX). So I think you'd have to go back to the 1920s (not 1930s because FDR did way better than this) to find a map with parts of South Texas being >90% Democratic and so many random rural counties going blue, and I say 1928 (when Al Smith's Catholicism gave Herbert Hoover an opportunity to, I believe, actually win TX) then because an unusually high number of counties went Republican given how solidly Democratic TX (every corner of it) was in that time period.
Anyway, here's mine:
