(CNBC) Brian Schwartz October 14 2019 Mike Bloomberg might end up running for president after all. Bloomberg the billionaire former mayor of New York has indicated to associates in recent weeks that Joe Bidens recent struggles against Sen. Elizabeth Warren are making him rethink his decision to stay out of the 2020 Democratic primary according to people familiar with the discussions. These people declined to be named because the conversations were deemed private. Bloomberg has signaled hes still looking at" running for president but people close him say that the only way he could even go down that path is if Bidens fortunes suffer so much that he drops out before or during the early stages of the primary. Bloomberg could then enter the race as one of the rare moderates with enough name recognition and campaign funding to make a run. Forbes estimates his net worth at $51 billion and he was planning to spend over $100 million on a campaign for president if he ran. I think its something he wants. He has not been shy about that" one of Bloombergs allies familiar with the talks told CNBC. Nothing can happen unless Biden drops out and thats not happening anytime soon" this person added. Hes like everyone else. They cant get it out of their system" said a banking executive who has known Bloomberg for decades. Bloomberg is in if Biden is out" said another New York billionaire with ties to Bloomberg.
