One of the hazards of single-party government: corruption.
Mediocrity, to boot. The Texas Republicans are starting to seem like that species of jellyfish that is only found in certain lakes and lacks any ability to sting - after thousands of years of having none of the natural predators that are found in oceans, they simply stopped needing to make an effort.
The deterioration of the caliber of downballot candidates in Texas really reached a tipping point in 2014. That someone like Ken Paxton - a man who, yes, did successfully graduate from law school, but whose career included no judicial clerkships or significant work in constitutional law, and who has spent the bulk of his career doing in-house legal work for companies and as a "financial advisor" - was a major party nominee for attorney general and was easily elected is a scandal in and of itself.
