US Presidential candidate Robert F. Kennedy Jr.
...is a joke, and should not be taken seriously. This guy spreads conspiracy theories about COVID-19 and other stuff. It's hard to believe that he will ever become the president or even win the primaries, when it seems that a large percentage of the Republican starboard supports an even more grim character instead (Trump).
Anyway, gold standard is dead. So even if he does become the president, he won't be able to tussle with the Federal Reserve to make a "bitcoin standard" because they won't allow him to.
