Unlike outdated, racist preconceptions, the area from about 200 miles or so north of the USMexican border isnt neatly divided into brown Mexican-descended people on the Mexican side of the border and Euro-Americans (and maybe a few token Afro-Americans) on the US side of the border: a more accurate description for the last couple of decades is that a MAJORITY of the folks on the US side of the border in that zone are of Mexican descent. And while racists might want to believe that the population shift is due to illegal immigration
, much of it is due to the fact that many Mexican-Americans are Catholics and have large families. (Just like Italian immigrants and Polish immigrants and Irish immigrants did generations ago). (Its called natural increase!)
(Of course the continuing right- wing assault on family planning clinics hasnt done much to discourage any unplanned pregnancies and more population increase).
Up to now, many Mexican-Americans were rather indifferent about national and local Texas politics, much to the despair of Texas progressives and Democrats. This may be changing, what with the Miller/MAGA rein of terror on immigrants and Mexican-Americans finding that Noems and Homans goons dont take pains to distinguish between immigrants and brown-skinned American citizens whove been here for generations or even longer.
Considering that Latinos are not only a plurality in Texas as a whole and outnumber European-Americans these days, this might not work out so well for Texas Republicans still pulling out memes and actions from their grandfathers racist toolboxes.
