Possible but extremely unlikely. 3rd party candidates rarely get any electoral votes.His support could grow enough where nobody gets the required 270 electoral votes. In that case, it goes to the House and each state only gets one vote. The winner needs a 26 vote majority to win. The Senate would vote on who becomes VP between the two receiving the most electoral votes. That would put RFK, Jr's running mate out of contention. Now that would be interesting. Both a Democrat and Republican serving in the WH.
