Near as I can tell, RFKJr is running as the anti-Biden. He’s famously very opposed to the mRNA injections, which Biden mandated. I think he’s also aware that while ‘RAT politicians favored the lockdowns, antisocial behavior, and mandates, a majority of Americans opposed them. I’m not sure if he seriously thinks he can obtain the ‘RAT nomination. If their elections were at all honest, Bernie Sanders would have been their 2016 nominee.
But, his first comments are blaming Trump.
