Robert F. Kennedy Jr. previously requested Secret Service protection, and Donald Trump endorsed that bid after getting shot at during a Pennsylvania rally.
He isn’t polling high enough for Americans to spend the money. For people that love to talk about fiscal accountability this is a major waste of tax payer money.
Some crazies and some of the sheep support him (I know someone who thinks he has some good ideas and would potentially vote for him in an election that didn't include Trump). It's hard to say how much support might swing his worm-laden way if Trump were no longer in the picture. He has no chance against Trump, though.
