Nobody thought Trump had a chance when he announced his candidacy, and RFK Jr. has some formidable advantages. From Jeffrey A. Tucker at The Epoch Times via zerohedge.com:

As predicted two weeks ago, Robert F. Kennedy, Jr., appears ready to declare as an independent for president. Already polling at 20 percent nationwide, he will announce that he is severing ties with the Democratic National Committee (DNC). This is because the DNC has set up impossible roadblocks to victory within the party apparatus and the primary process. The Biden administration is denying him Secret Service protection despite apparent attempts on his life.

Of all figures in public life today, RFK has the strongest claim to the legacies of his father and uncle, ideologically and culturally. That would put him in the solid category of a real Democrat—half a century ago. Times have changed and dramatically so. He started off this campaign with the belief that he would help guide his family’s party back to a principled commitment to the common good. But he has discovered that this is not what the party is about anymore, at least not according to the masters at the top.
This is a man who believes that America is not lost, not foundationally corrupt, not a complete goner. He looks around at the people in this nation and sees goodness, love of country, a desire for freedom, and a strong devotion to make things right. Conventional American politics, however, seems designed to block real solutions. Because he still wants to make a difference—one senses that he believes it is his destiny—he will continue his run for president as an independent.
Perhaps, maybe, possibly, hopefully.
