I would say, though, it is early. You could have a lot of big surprises, a lot of action between now and the first Iowa caucus and the New Hampshire primary. A lot's going to happen in the Republican primary, and I think some things could happen on the Democratic side as well.
All that New Age stuff that seemed so weird when Brown ran for president the first time (in 1976) is still part of his repertoire. But he’d be helped if he ran by the extent to which yoga and brown rice and so on have become part of American culture. Jerry Brown hasn’t gone mainstream (or at least not much), but mainstream has gone Jerry Brown.
