Plenty of states already have regulations. California has rules about how parties elect their boards and whatnot, for example, and officially recognizes parties. I agree that we should reduce their influence. That would be the opposite of doubling down on our current system of treating them like pseudo-branches of government. One way to accomplish that would be to ban official recognition of parties, require them to fund and run their own primary elections, and move to multi-member representation districts. All of these things can be done at the state level for state and local offices.
