John F. Kennedy Jr. would be the only acceptable President of the United States as an alternative to Trump, by both the democratic & republican voter base. He'd also be the one person that could give full declass to the public & NOT have the information be rejected by the masses, dismissed as "Conspiracy theories" & attacked for being "mentally unstable".
When a Kennedy speaks, the entire world turns its head & perks up its ears. JFK Sr had the exact same je ne sais quoi.
I'm a firm believer that JFK Jr is still with us, but at which point will that be disclosed, can only be speculation.
