The 10th amendment to the US Constitution says the following.
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
When Obama or Biden is in office Democrats seem to believe in a strong federal government. States that oppose the power of the feds over their state's rights are Neo-confederate racists. But something magical occurs when the Democrats lose power. The suddenly discover states rights! This is playing out all over again. Its fun to watch these clowns expose their hypocrisy.
Gavin Newsom is "Trump proofing" California he says. He's also changing his tune on many other issues but that's another topic(in his preparation to run for President in 2028).
The Republicans play the same game. When they hold power many of that party want a nation ban on whatever. They suddenly don't care about the 10th amendment.
If you can't see this hypocrisy in both sides you might need to unplug from the Matrix for a while. Its interesting to me that after over ten years of not being on either side how blind partisans seem to be about reality.
