The Supreme Court is heavily in favor of “states rights” now, so state politicians know they can cater to special interest groups (for donations of course) with impunity. States are heavily gerrymandered, so they have little risk of losing their position. In some cases, such as book, education, voting, and immigration laws, the goal is to further ensure the states remain Republican in the future (prevent children from growing up “woke,” and prevent immigrants from living there, which tend to vote Dem). Democracy in the U.S. is pretty broken, and is slowly being dismantled further.
