I'm not sure of your understanding of America's government.

Conservatives control all three branches of government to an extent. The Senate GOP doesn't have 60 members, so the Dems can block legislation (the GOP hasn't invoked the "nuclear option" that would prevent that). That's why there's a government shutdown, 100% of that is on the Dems.

The Supreme Court exists only to interpret law in terms of constitutionality. Even with a conservative majority, it shouldn't, and almost certainly won't, violate the Constitution.

As I said above, events leading up to the midterms, and the midterms themselves, will determine the way forward...quite democratically. :-)
