using the governor race as a bench line is like using the Ohio senate race to show that Ohio is still a swing state. Lupe Valdez was a god awful candidate who didn't even bother campaigning and no one paid attention to.
Except that OH has went from blue/purple to red and continues to elect all Rs save for 1 due to his popularity, and TX has went from red to lighter red and continues to elect all Rs. Meaningfully, there's been no change in TX where it counts in these statewide races.
It's not necessarily using any race in particular (though that was the most egregious example); you can't be a swing state or purple state unless you've actually "swung" lol (which TX hasn't yet).
Governor's races don't match up much with national politics. It wasn't just Cruz and Beto, but the Democrats also only lost the House vote by about 3% too.
I'd say it's a case of a reasonably popular governor being able to to distance himself from the national environment, and seeing the state trend toward Democrats again otherwise.
This seems to have become a very popular talking point on the forum this cycle, which is surprising, given that there's more correlation between the 2 now than at any point in modern history. Obviously there are states that can simultaneously tilt in both directions depending on the type of office and specific candidate, but when non-toxic candidates of a party that has been winning unilaterally for decades in a state can still pull hefty double-digit leads despite
hordes of literal straight-ticket first-time voters being brought out, then it's premature to say that a state is becoming "blue" (or even purple). Jim Martin lost by the same amount that Beto did in GA 10 years ago and the state still hasn't went Democratic in a statewide contest.
There's a very good chance these margins collapse in the next election when candidates who aren't Beto can't turn out all of these immensely low-propensity voters and the straight-ticket voting option is removed from the ballot.
