Bloomberg is convincing the Democratic power brokers and big donors that the Biden fantasy is over. Either they support him or they get the communist Sanders. Bloomberg may not defeat Trump and much of the progressive base will be infuriated but a Bloomberg candidacy would probably prevent a Democratic debacle in Congressional races. Also Bloomberg is probably offering Biden’s best people jobs in his campaign.
But Sanders will probably win big in New Hampshire. Bloomberg either proves he’s credible on Super Tuesday or Sanders will be unstoppable and the disastrous Democratic nominee.
Bloomberg may sound persuasive to power brokers but he will be burnt toast in any major state primary.
Astroturfing (media campaigns without grass roots support) has never worked yet in either party.
In addition the guy is very unappealing in every possible way—to everyone!
