This is true on all sides of the aisle. If SBF hadn't tried to speed run every crypto-scam he might have some political connections left. But he's not just persona non-grata, he's broke. He doesn't have much to offer politicians at this point except testifying against co-conspirators (should there be any).
I personally do not think the Dems care about a broke crypto dude who can contribute nothing to them and didnt exist 3 years ago.
