Another new york billionaire, flirting with the president ial run, former mayor michael bloomberg, democrat turned republican, turned independent. So we will turn to our cbs news political director and anchor of face the nation john dickerson. What do we know about bloombergs plans . He is seriously considering jumping into the race. Long wanted to run for president. He would run if it looks like it is going to be a general election race between donald trump or ted cruz and Bernie Sanders. He believes those representatives of the wings of the two parties would create an appetite for a candidate in the middle who is fiscally conservative and socially liberal. The challenge is to collect the signatures to get on ballot process starts march 1. There may not be a clear signal about either party by that date. What are some obstacles . He has no party the he has no organization. He would have to build all of that from scratch. Democrats and republicans start with a huge lead in Electoral College votes in a lot of the states that traditionally vote for those parties. Bloomberg would have to compete on a much bigger Playing Field than democrats or republicans because he starts with no states in his column. And that kind of a campaign would require a brushfire, tended by a charismatic politician who could rouse people and keep them excited for months. Thats not the kind of politician he is. He is more known for his policy ideas than his stirring speeches. John dickerson, anchor of face the nation. Watching you sunday. Thank you, john.

But nowhere has the damage been more threatening than in pacifica. I love it here. This has been my dream all my life to live by the ocean. Like right by it. Reporter pacifica has seen it all before. In 1998, the last time, major el nino storms hit california. The bluffs here eroded so quickly. Residents fled before one home tumbled into the ocean. Other houses were knocked down before they too fell off the cliff. In 2010, two of the Apartment Buildings on the bluff were evacuated and condemned. The building condemned today seemed safer until the cliff again began falling away. The powerful winter storms that have been hitting california are predicted to continue into march.
