One step Republican legislatures fear to take is the use of the power of the purse strings to curb the Marxist and liberal domination of state-run universities. The last time anything of this order was done was in the 1950s, and the liberals screamed about repression and McCarthyism, and generally the legislatures backed down. In Texas, for example, both houses of the Legislature and the governor's office are held by the GOP, yet the University of Texas system is notoriously liberal, and has been so for decades. Similarly, not since the Reagan Administration have Republican lawmakers seriously attempted to cut off Federal funding for leftist dominated groups like the National Endowment for the Arts and PBS. OTOH, the liberals when in power do not hesitate to attack institutions where conservatives dominate, for example, in the feminizing and homosexualizing of the military and the use of the IRS to harass conservative organizations.
Conservatives must storm or topple the ivory tower of the liberal educational and cultural elite. Without that, any victory on issues like firearms ownership, Supreme Court justices, etc., is only temporary. You can win a lot of battles yet still lose the war, as Jefferson Davis and Robert E. Lee would have attested.
