And then there were four.

Bill Richardson is planning to drop out of the presidential race, according to AP.

“The Richardson campaign would not comment on the governor’s decision, reached after a meeting with his top advisers Wednesday in New Mexico.

“Richardson had one of the most wide-ranging resumes of any candidate ever to run for the presidency, bringing experience from his time in Congress, President Clinton’s Cabinet, in the New Mexico statehouse as well as his unique role as a freelance diplomat. As a Hispanic, he added to the unprecedented diversity in the Democratic field that also included a black and a woman.”

Richardson also injected humor into the race, whether in his 30-second “job interview ads” and debate appearances (“I’ve been in hhostage negotiations that are a lot more civil than this”) and in his personal appearances. There was an informal quality to the candidate and his campaign that was perhaps in contrast to the scripted methods of his competitors.
