175.10 has been used before. There are many things which are firsts, and a lot of shaky legal theory. My I'd put 10 to 1 odds this gets overturned, and 5 to 1 odds it happens before it gets to the supreme court.
1. Usually they charge the predicate crime.
2. FECA has never been used as a predicate crime.
3. I don't believe a campaign finance reporting violation has been tried as election interference.
4. There are a lot of unsettled questions about these laws like can 175.10 point to a federal crime? Is hasn't been prosecuted that way before. Can it point to FECA despite FECA's broad preemption?
