Kennedy could make this next election quite interesting. Not that interesting elections are a good thing. (Same goes for the uninteresting ones.)

He is there to peal votes from trump as an independent.
The only reason RFK Jr isn’t leading in the polls is that not enough people know that he is running. They can’t keep it secret forever.
