1. Biden is already dead in the water - he can't campaign without insulting people. BUT
2. Bloomberg hasn't even appeared on the ballot yet, so only a fool would make predictions about him now. Sure he's got a ton of cash, but so has Steyer, and he's spent it too, and it's done squat.
3. Warren (whom the press are trying their hardest to pretend doesn't exist), Buttigieg and even Klobuchar have done better than Biden (or Bloomberg, of course).
Those "some" consist of Republican trolls, hoping it'll scare their geriatric voters. And possibly just morons who don't know what the word (communist) means.
