General Discussion

In Texas, you do not register to vote by party. Texas is an open primary each voting cycle but once you vote in one party's primary, you are locked into that party's primary for the rest of the two-year voting cycle. That means that if you vote in one party primary for the first round of voting, then you cannot vote in the other party primary for any runoff races. Many local races are non-partisan and there are no primaries but there are usually runoffs if no candidate gets a majority of the vote. There may have been some cross over voters in the past, but Texas has not elected a Democrat to statewide office in about 30 years and so most people stay in their own party primary. Here there are competitive races in the US Senate seat for both parties and so I doubt that there is much crossover. From what I have seen of the GOP senate polling, it is very likely that there will be a runoff in the GOP Senate primary race. If a GOP voter crossed over to vote in the Democratic primary, then that voter will not be able to vote in the GOP senate runoff.

One of the factors that give me hope that Texas is slowly turning blue is the demographic composition of GOP voters. Texas is getting more urban and younger which is not good for the GOP
