He’s paying a person $47 for every registered swing state voter that that person refers to the SuperPAC and that follows through on signing a petition to support first and second amendment rights.

It appears to be lawyered loopholes around paying people to register to vote directly. Which is illegal as you mentioned.

Sure plenty of people will sign it for the money and then forget about it, but some sliver of people that sign will feel some sliver of obligation to vote for the candidate that the petition obviously wants them to vote for. A sliver here and there could be enough to turn this currently close election.
