Texas doesn’t register voters by party, but....
In 2016 there were twice as many votes cast in the Republican primary as in the Democrat primary. Both primaries were contested of course, and native son Ted Cruz was running on the R side. There were 1.4 million Democrat votes as compared to 2.8 million Republican votes.
Just 4 years later, Democrat primary voters OUTNUMBERED Republicans, 2.094 million to 2.017 million. Obviously the Democrats had a contested race and our side did not, but still....
And of course there was a bloodbath at the U.S. House level in Texas in 2018 (with a net loss of another 2 to 4 Republican seats to come in 2020 if things go really bad; best case is probably +1) despite the narrow statewide win of Cruz and the less-narrow but still unimpressive win by Abbott against a complete non-entity Rat candidate.
Texas is getting pretty damn purple these days and is heading more in the red (to use the proper color for the Commies) direction by the day.
To be fair, I know I wasn’t the only person to switch to voting Democrat in the primaries. Even though I have voted GOP my whole life, I switched to Dem in the primaries both because I saw Biden as a weaker candidate and Bernie scares the crap out of me, even more than Biden. Funnily, I never had a single pollster reach out to me in my many years as a Republican. In the few months the books has shown me as a Dem (I am switching back next election) I have had no less than 6 pollsters call/text me... hmmm
