If RFKjr has repudiated his past love of Marxist dictators (Chavez\Maduro) & Fascist approaches to environmental issues\Global Warming. (Wanting to put energy company CEOs in jail for just being energy company CEOs is pretty Fascist!) then he’s redeemed himself. If he hasn’t then he has not! Until proven by actions he’s just another professional politician who has found a new worm to dangle in the water to hook some support.
I don’t think he has to do that. If he only works with Trump on the list of issues he has named that they agree on - endless wars, border security, free speech, reigning in the deep state agencies, and fighting big pharma and the chronic disease epidemic to name a few - that proves my point.
Do those things and we’ll still have a country left to argue about the rest in.
