The conservative values may predominate for longer than the conservative majority, due to voter suppression and gerrymandering by the state. As one example, I read an article describing a program to reduce voter registration in Texas (this was maybe 2 years ago, so my memory will be imperfect). Someone registering voters has to be from the same county or district as the voter, and has to follow a sizeable book of regulations. Violations are felonies. This makes voter registration drives very difficult. These tactics and others like them are not novel; they existed before the Voting Rights Act of 1965. After the Supreme Court in 2013 effectively ended the supervision of states by the federal government, the tactics returned in many of the formerly segregated states.
