I think like most candidates he is setting himself for 2024. He needs to be seen challenging Trump. Our system isnt going to be any less broke without Trump.
I have yet to see anything on his website to say what type of campaign he wants to run. But he has to establish himself first. As an independent he cant sell his support like the Ds did to gain a job that gives them credibility going forward.
The type of math we saw in the last election says we arent far from seeing these smaller guys steal an EC or two. And once that happens the babies who cry about their validity will have something new to consider.
Third-party candidates took a small but significant chunk of votes
Even just weighting the scales a bit will help gain recognition. Especially if we see more faithless electors.
