The Republican field, announced or expected, seems to consist of multiple non-entities, a political ameibomorph from Massachusetts (or is he from Utah ? or New Hampshire ?), Obama's former ambassador to China, a former House Speaker whom Bill Clinton took to the cleaners politically, Rudi, and a half-term governor from Alaska who has yet to do serious study of the issues and/or prove she deserves to hold any higher office.
I rest my case.
UPDATE 5/18/2011: BTW, ameibomorph means 'shape-shifter'.
