“All of a sudden “state’s rights” is cool.”
Unless you mean gun rights, “gay” marriage, etc.
As a consequence of many generations of parents not making sure that their children are being taught about constitutionally enumerated rights versus 10th Amendment-protected state powers, or the differences between legislative and judicial powers, voters don't understand the following about so-called gay marriage rights.
They don't understand that since the states have never amended the Constitution to expressly protect gay "rights," that pro-gay activist judges are wrongly legislating such "rights" from the bench.
