We’ll believe it when we see it: The Huffington Post’s Howard Fineman reports that New York City Mayor Michael Bloomberg and MSNBC host Joe Scarborough have discussed a 2012 independent bid for the White House. Bloomberg would take the top slot on the ticket, Fineman says. Scarborough says, "We haven't discussed it directly. Have people discussed it in his sphere and in my sphere? I think so." Bloomberg’s aides declined to comment and Scarborough ridiculed the report on Morning Joe Wednesday.
