Add a Michael Bloomberg to the democrat campaign train.
Get ready for a mass exodus from the clown car.
If he files for Alabama and not for NH or SC, then he is not in it to win, just to impact the race.
But I don't think most of the "lower tier" candidates will have their decisions impacted by Bloomberg's choosing to run. The people he most directly impacts are Uncle Joe and Mayor Pete.
OTOH, as Harris and Castro cut down on NH expenditures (among others), Tulsi is stepping up there, prompting a bunch of folks to ask where her money is coming from, when this is added to her billboards all over Iowa.
Bloomberg is likely to be better received than De Blasio or, when they were candidates, Giuliani or Lindsay, for that matter. Ditto the various LA mayors who have taken a brief gander at the presidential sweepstakes. But... "better received" is not the same as well-received. There is no hunger for a Bloomberg candidacy, except perhaps among Bloomberg associates.
He's not Tom Steyer - name recognition, at a minimum, is far more there for the New Yorker. But... Bloomberg is no more a Democrat than Sanders is. He has a better chance of stealing some Trump-resistant GOP members and independents, should he run in the states that permit party-crossing or independents to vote without losing their status. (I live in a latter state.)
But he is also not H. Ross Perot. His billionnaire status won't make him a top Democratic candidate and he isn't aiming at the 3rd party gig, so he's got less of a shot than Perot did, despite his being a lot less... of a paranoid loon. And Bloomberg has a record that will make it hard for him to take the votes away from Biden - "Stop and Frisk" is chief among them.
(This, while a reply to one of Ward's posts, is a sincere post for those of us who actually give a damn about this country and the Democratic Party's nomination process.)
