Not really as conservative as you think. Texas is an overwhelmingly Republican state (there are no elective positions held by democrats that are voted for on a state-wide basis). All the 'smart' democrats changed to the Republican party (like our current gov, who used to work for AlGore). You can't really tell much about a Texas legislooter by looking at party affiliation.
The GOP Caucus in Texas is a lot more conservative than a few years ago. The Tea Party has been fantastic at vetting RINOS and Republicans that are just Democrats who changed to keep seats, and replaced a lot of them this election. And it’s just the first stage. The RINOs are not nearly as powerful as they were because of the message this election. Voters aren’t wanting moderate RINOS, they’re wanting conservatives. RINOs and former Democrats know this that’s why they’re scared and actually breaking laws to keep power. The People of Texas are a very distant second to their lust for power and keeping what they have and getting more.
