GOP flips in 2020 after Dem 2018:
CA-39: 39%
CA-48: 42%
This district's Democratic trend is mainly because of changing demographics, not Rs switching sides like the more educated suburbs. Lower propensity voters in these places tend to be Dems, hurting the party in off year elections. CA-25 is a perfect example, 26% with college degree or higher and Dems completely struggled in the special election (lost by 10) but Biden still won by 10 in the fall. Of course Smith was an awful candidate and Dems couldn't win the House seat but it was a coin flip.
My point isn't that Dems will win or lose the House, it's that districts like TX-6 are not as good for them in non-presidential years. For the GOP, I would throw out PA-8 as a good example that is probably better for them in presidential than a midterm. TX-6 is is SIGNIFICANTLY less educated than districts the Dems have recently gained. Just because it is suburban and Sun-Belt doesn't mean it is the same.
some other data about this district;
1. 34.5% of whites in the district have a ba or higher (ranking 212th out of all CD's, slightly below national %)
2. average white income is $80,090, ranking 126th in the nation.
3. Tarrant county's blue suburbs and white precincts also showed far more republican votes in this low turnout special
While doomsday is silly, this is not a good result for democrats, no matter how you try to spin it. this is a district where they should do well, even with a fragile turnout coalition.
