SANTA FE New Mexico Gov. Bill Richardson cast his vote Tuesday in the state's Democratic presidential caucus, but gave no hint as to how he marked his ballot.
"Just going to keep that to myself. They're both great candidates," he said while standing in line to cast his ballot at a community complex just north of downtown Santa Fe.
Hillary Rodham Clinton and Barack Obama have actively courted Richardson's endorsement since he dropped out of the presidential race Jan. 10.
"I'm just going to hold off on any endorsement," said Richardson, who waited in line for about 10 minutes. "Looks like good turnout."
Richardson declined to say whether he thought Clinton or Obama would carry New Mexico.
"I think it's going to depend on turnout and who has the strongest organization, but I know it's very close," Richardson said.
