Though maybe some of the other things Musk was doing were of murky legality, this one is clearly illegal. See 52 U.S.C. 10307(c): “Whoever knowingly or willfully gives false information as to his name, address or period of residence in the voting district for the purpose of establishing his eligibility to register or vote, or conspires with another individual for the purpose of encouraging his false registration to vote or illegal voting, or pays or offers to pay or accepts payment either for registration to vote or for voting shall be fined not more than $10,000 or imprisoned not more than five years, or both…” (Emphasis added.)

I mean, if it’s clearly illegal then can we, you know, apply the law?
