>>This would likely “de-federalize” 7400 of those 8000 cases going to the SCOTUS every year.<<
When I review just who is elected locally and where their policies have taken us I am not confident they would appoint conservative judges to the 2nd Court, composed of 100 State judges. Looking at state senates and seeing the difficulties they are having reducing their state budgets is reason for further concern.
Oddly enough, there is considerable bipartisanship at the State level when faced with federal overreach. This is because State power and federal power are in conflict—for the federal government to have more, the States must have less. And the States don’t like this one bit.
This again shows the brilliance of the founding fathers. Even at the federal level, when the president is of the same party as both houses of congress, while they might get along on overall policy goals, when it comes to a conflict between the powers of the branches, they are often at loggerheads—the desired state, as far as the founding fathers were concerned.
And this is exacerbated in the fight between federal and State power, so much so that right now, blocs of the States are forming around all sorts of anti-federal issues, loosely called the 10th amendment movement, as an umbrella term.
