It's for real, she's running.
I wonder what her chances are. I have no idea how to call this one.
I could see it happening, though. She's the kind of person that can stir up real enthusiasm. She's incredibly smart, incredibly funny and has come around to extremely reasonable positions that sound like a good fit for the California electorate. Pretty powerful combination.
And she had enough celebrity status to announce on the Today Show. (So sorry about the posting delay. She said she was going to announce at 10:30 PDT in South Central. So I kept waiting till then to check the wires, and then I got distracted, because I get distracted by everything.)
Early stories from AP and San Jose Mercury News. More info at her new website.
Oh, and Diane Feinstein announced she's definitely out. (So she says, though this one sounds more convincing. The AP story has some details on that as well.)
