I think it would be prudent to disengage democrats from being 'left wing'. There is certainly a progressive wing of the democratic party, but none of those are the people he donated to. After all, this is the Democratic Party that a couple years ago during election season were trying to get George Bush and Dick Cheney to come to Kamala's rally.
He also secretly donated significant amounts of money to republicans (self-admitted), so all-in-all his contributions definitely skew center-right.
If everything is so secret then I'm confused why were discussing it. All this "secret" stuff is coming from a convict in a prison cell?
Tbis is a guy who believes in Effective Altruism. Thats not progressive thats a hard left turn. Especially when the road to get there is commiting crines.
