Just another delusional member of the political class.
This guy has absolutely no chance, zero, zip, nada.
With Booker and Harris cratering, he's jumping in to fill the "person of color" role in the clown car. He probably figures to bring in a few million in donations, make a few appearances in nearby New Hampshire on the cheap, then drop out as soon as he can.
He is probably there for a VP candidate - and was probably asked to do this by party leaders. The popularity of Trump will black voters - especially MEN - will sink the Dem candidate in the 2020 general election. Trump’s border issue resonate with many blacks thinking of themselves as AMERICANS; like others, they are tired of being surrounded by people jabbering in foreign tongues. For blacks in particular, many of these foreign scabs end up as their supervisors; the animosity is palpable (both ways).
The party leaders looked for the best token and came up with him.
