Richardson, who dropped out of the Democratic race in January, is to appear with Obama on Friday at a campaign event in Portland, Ore. Take that Clinton Team!!
It is an important endorsement on at least three fronts. Mr. Richardson is an influential superdelegate for the party, whose declaration of support could draw the backing of other superdelegates needed to secure the nomination, since neither candidate seems likely to win it through delegates earned in the primaries and caucuses. He was a prominent second-tier candidate before the race narrowed to the two frontrunners, and as such has been courted by both campaigns since he dropped out. And he is the country's only Hispanic governor, and could thus help Sen. Obama with a key bloc of voters that has mostly leaned toward Sen. Clinton. Mr. Richardson, who praised Mr. Obama's national-security credentials to the AP, also brings the foreign-policy credibility that came with being ambassador to the United Nations, energy secretary, and global trouble-shooter for the presidential administration of Sen. Clinton's husband.
