New Mexico Governor Bill Richardson plans to announce he's leaving the race for President Thursday. Top campaign sources, speaking anonymously confirmed the decision tonight. Richardson brought an impressive resume to the campaign, serving as President Bill Clinton's UN Ambassador and Secretary of Energy, but never posted more than single digit results in the voting, and could not bypass John Edwards as a potential third-place finisher.
Richardson may opt to run for an open Senate seat in New Mexico, with this year's departure of veteran Senator Pete Domenici. But he still has two years left in his term as Governor.
