If the options for President are
1. A petulant child who abuses his office
2. A dementia addled man who is being controlled by unknown people behind the scenes
3. A “kooky” but otherwise mentally sound individual who isn’t bought and paid for by lobbyists and corporate interest
I don’t know how anyone can say option 3 isn’t the best of the worst. If it really ends up being Trump vs. Biden then supporting RFK Jr. is an easy decision.
He's more coherent than Biden and Trump, but I disagree with the mentally sound part and would not want a president dabbling in conspiracy theories which are easily debunked and who hides behind statements like "just asking questions" etc..
In any case though, he does not have a chance to win so the options for who will win the presidency will not be between those three. There may be another candidate I would support but having a chance to win by pulling support from both sides but without a 3rd party with an actual chance to win I will be choosing between who I prefer between 1 and 2.
