(CNN) - Barack Obama picked up another superdelegate Friday, narrowing Hillary Clinton's advantage to three.
Democratic National Committee Member Ed Espinoza formally endorsed Obama, saying he has "the character to lead our great nation."
“I am endorsing Barack Obama today because throughout this process I have seen him show a judgment and character that we need in our next president," he said in a statement released by the campaign. "From day one he opposed the Iraq war and has a plan to end the war in a responsible way and bring our sons and daughters home."
Espinoza is a former supporter of New Mexico Gov. Bill Richardson's presidential bid.
