The AP reports that New Mexico Gov. Bill Richardson is ending his campaign for the presidency “after twin fourth-place finishes that showed his impressive credentials could not compete with his rivals’ star power. Richardson planned to announce the decision Thursday, according to two people close to the governor with knowledge of the decision.”
UPDATE: According to MSNBC, the Richardson campaign is denying the AP story.
UPDATE II: MSNBC has now reported that Richardson plans to announce his decision to drop out on Thursday.
