Someone said earlier that Pete would probably take away votes from Ellison, not Perez. In which case, supporting Perez would make little difference (or in fact, would probably embolden people to NOT support Perez, if anything).
I was just responding to that sentiment.
I find that a bit doubtful, given a lot of people who support Perez (using this thread as a case study) have been very impressed by Pete.
No doubt Dean, a previous chair, was as well. I suppose it's theoretically possible he threw support behind him in some crazy attempt to sabotage Ellison (because reasons), but it's far more likely he liked Buttigieg enough and saw him as someone with a lot of potential in the democratic party.
Not everything has to do with money. Everyone on that stage tonight, and Dean all care about the future of progressiveism and the democratic party more than any single policy they choose to enact.
