Yeah , I wish they would have retired Nancy Pelosi by now , she is the symbol of what all is wrong with the Democratic Party. I do think Tom Perez has a decent shot at DNC chair , he does seem a bit more focused on jobs etc than the fantasy wing of the party. Whatever the fantasy wing ultimately wants, there are enough biz connections into the party (think Buffet, Gates, etc) that I don't think actual policies match the rhetoric.
Hillary's arrogance was a factor , I agree on that. Although I have always felt that Dems bring a knife to a gunfight. By that I don't mean being as vulgar and ugly as Trump, but letting loose and injecting humor and quick reaction (which again, Bill Clinton was a master of) as opposed to relying on 29 point policy prescriptions.
Maybe Greg Popovich ? Mark Cuban ? Who knows
