Leahy and Durazo Aboard.

"'We need a president who can reintroduce America to the world – and actually reintroduce America to ourselves. Barack Obama represents the America we once were and want to be again." Sen. Patrick Leahy of Vermont endorses Barack Obama. "Leahy likened his support of Obama to the 1968 presidential campaign, when as a young prosecutor he endorsed Robert Kennedy over Hubert Humphrey. 'He was bringing us a sense of hope, bringing us together,' Leahy said. 'I know those are intangibles, but it encouraged me to go against the establishment in my own state, and go with Bobby Kennedy.'"

And another potentially big Obama endorsement from yesterday: Maria Elena Durazo, head of the Los Angeles Federation of Labor. One expert said of Durazo: "There is no person in all of California who could get more people out to the street to go do something, either to march or get the vote out." "When she discussed her endorsement with her son Michael, a senior at Cathedral High School in Los Angeles, he urged her to choose Obama. 'He said, "In the end, Mom, it's the chance of a lifetime." For him to say that means a lot. It's true.'"
