That's pretty big news for him, and a real shot in the arm after the week he's had. Richardson is the only Hispanic Senator in the country (New Mexico). His endorsement might help swing Latino voters who are still "on the fence."
The most surprising part is that he's very close to the Clintons, who have to be reeling over his decision to back Obama.
Weeks back, when Richardson wasn't willing to endorse Hillary, she reportedly* yelled at him on the phone, saying: "Two presidential appointments wasn't good enough for ya?!?!?"
