Technically, the equivalent would be you standing outside a polling place with a sign saying “I will give every adult in the area $500 if Candidate X wins”.
Ostensibly, you could just be lying (just like Trump) - and that would probably be covered under your 1st Amendment rights.
It’s stupid, but there is enough of a disconnect between action and reward that it might skirt past.

Here in Melbourne, Australia - the diesel price is currently the equivalent of $8.60 USD / gallon ($2.65AUD / litre).
