Texas is such an electoral handjob for Democrats. It's always almost there but it never quite gets the result we're looking for.
I wouldn't describe it as that, though. It's only been single digits in terms of races twice in the past several years, and 2020 is the first time it was even properly considered semi-competitive in a presidental race in a long time.
If anything Democrats have a lot of room to grow in the state. It's just that turnout dynamics do not currently favor them in the state, and it depends on a lot of factors.
Also, remember people said the same thing about Georgia prior to 2020, so anything can happen.
