From where I sit, Bloomberg basically seems like a Bush-era "Never Trump" Republican who I'm guessing is running as a Dem b/c it's likely his best chance of going against him. (just ask Joe Walsh where running against him as a Republican gets you). May be relatively (marginally) more liberal, but seems like just another Neoliberal centrist to me. And supporting the Patriot Act and Bush's bs war in Iraq? No thanks.
Dude is buying his way for a top spot but at some point you need actual support from actual people and I don't see any of that yet.. If he's Bernie's "final challenger" it would have to take an incredible amount of rigging and manipulation to somehow get him over the top past Bern.
