Yes yes, we all have our post hoc excuses for why a state with a historical trend toward the Democrats didn't continue on. All of those excuses were happening when Florida was getting bluer. It'd be great if all we needed to do was kick our feet up and demographics would solve our political problems, but this isn't a new idea. People in 2000s thought the Democrats would have a permanent majority by now. Turns out the money behind the Republican party isn't going to just sit back and let them wither into nothingness.

In 10 years we'll have a good excuses for Texas too. It will be obvious that some Hispanic group was going to turn conservative because they were fleeing failures in nominally left wing states, or were very religious, or had a machismo culture or something. The young people moving to Texas for economic opportunities will be scared away by the abortion bans. Or they'll crank their media propaganda to 11. Or maybe Texas really will go blue and we'll have an entirely different set of turning-point states. The Democrats weren't doomed to be unable to win the presidency because Florida is no longer a swing state and somehow after all the Republican's failures and odious behavior we're still in a toss up now.

If it was a simple matter of waiting for Democrats to break the cycle and win forever, it would have happened by now. People have been predicting the impending collapse of the Republican party for decades.
