The federal government will not allow such an ad to be run no matter what the state says.
If federal law says something like, "Private organizations shall not advertise their candidates platform within 30 days prior to an election", but the state allowed it as a free speech issue, the state would be found in violation of the Supremacy Clause, yes?
I mean, I'd like to believe you, but I don't.
Correct, Federal law applies everywhere in the US. CFR applies to Federal offices, BTW.

NO!
If a State has no law on its books regarding election advertising, it is legal under State law, correct? Are you saying if a State does not make it illegal, they are in violation of the Supremacy Clause?
Is Vermont in violation of the Supremacy Clause because weapons banned under the 1994 AWB are legal under Vermont State law?
The feds can't make laws regarding local elections, only federal elections. States have their own laws and are not required to be as oppressive as the federal government.
