That's incorrect, friend. The Constitution declares itself the Supreme Law of the Land. It vests execution of the law in the Executive and grants the Judiciary power to decide all cases in law and equity that arise under the Constitution.
I qualified my statement with the exceptions in the Constitution limiting the states and individual cases related to the Constitution that may be brought on a case-by-case basis to a federal court. Those are the only exceptions.
Confirmed by Slaughterhouse, the original intent of the post-civil-war reconstruction-period 14th Amendment ONLY limits state segregation laws against blacks, former slaves. That's it.
