why is it the US is hellbent on making everything a state by state issue but at the same time saying federal law is above state law in such cases like Texas but states with legal cannabis or states with legal abortion are allowed to be above federal
The things that the federal government is responsible for are laid out in the Constitution, everything the Constitution does not place into the responsibilities of the federal government is left to state or local authorities.
Tenth Amendment:
Each state retains its sovereignty, freedom, and independence, and every power, jurisdiction, and right, which is not by this Confederation expressly delegated to the United States, in Congress assembled.
IDK why people are downvoting you, that's essentially how it works. Everything is super interconnected now, but it wasn't always that way and the constitution hasn't been updated to reflect it.
