The US constitution is a limit on federal power. The first draft of the first amendment was rejected because it was thought to be in conflict with the then established state churches, which the founders did not want to interfere with. Since Lincoln expanded the power of the central/federal government and displaced states rights, the equal protections clause has been abused, much like the commerce clause, to expand the reach of the federal government.
It is doubtful that Sohomeyer is a federalist. She is most likely trying to be clever and signal that when it comes to limiting the second amendment, it may be advantageous for the federal government to respect states rights.
