Compared to Trump, no, dude's pretty solid. I don't even think he's a racist like a lot of people do. I think he instituted racist policies guided by what he thought made sense at the time, and wouldn't surprise me if they even worked, but that's shown that he'd sacrifice civil liberties to get shit done.
Moderates such as myself don't want some one center right now, because we need someone to dismantle Trump's abuses and bring us back to center. Bloomberg would probably have the skills to minimize the economic shit show Donald will be leaving us with, but I doubt he'll tackle the pervasive & encroached corruption Trump's left us with.
As to Bernie not having a shot, I disagree, they've been saying he didn't have a shot since Biden was around. America's mistake is being so arrogant to think a left wing populist cannot take the WH, having learned nothing from our arrogance of thinking a reality tv host turned right wing populist would ever take the WH.
One thing's certain, righties are panicking & want lefties to pick Bloomberg because that reality (Bernie taking the WH) is beginning to set in.
