I agree with Bozo, it works better on a local level than it does statewide. The primary to replace Bryan Slaton, House District 2 had a 'jungle' primary. All candidates were on the same ballot, regardless of party. So that meant there were no individual party primaries. Texas does not register you as a D or R or L, that only happens when you vote in one of those parties' primaries. If you vote in the Dem primary this cycle, you cannot vote in any runoff other than a Dem one. And same for Red side. You cannot hold county or precinct chair positions or be a delegate to the state convention if you vote in a republican race. There are a few other implications, but those are the major ones.
In a jungle primary there is no party association, so people can cross over during that primary. This happened in HD 2 where once the local Dem candidate, Kristen Washington, did not gain enough votes to make the runoffs, many of the local Dems went in and cast votes for Jill Dutton over Brent Money. Money had been endorsed by the 3 evil stooges. Money did not get sizeable donations from outside the districts, ala Dunn, Wilks or any others. I guess Abbott and his klan calculated their endorsement alone would win the day.
So that was a short term win, and Dutton is no prize, but she's lengths better than Money. But now they are all on their party ballots again for the 24 primaries, and Dutton will serve out the rest of this term until 1/25 no matter who wins the primary now.
Even locally like that, it was only like 100-120 vote difference. It will be interesting to see the results of a normal primary.
