Obama nabs key endorsement of John Kerry

By Andy Sullivan

CHARLESTON, South Carolina (Reuters) - Democratic White House hopeful Barack Obama picked up a major endorsement on Thursday, with the party's 2004 nominee John Kerry announcing he would back his U.S. presidential bid.

Kerry's endorsement was a snub to former North Carolina Sen. John Edwards, his vice presidential running mate in 2004, who is also running for president but is a distant third in national polls to New York Sen. Hillary Clinton and Obama.

As Kerry was offering his support to Obama, the Illinois senator who would be the first black U.S. president, the Democratic field of candidates decreased by one as New Mexico Gov. Bill Richardson dropped out of the race.

Obama and Kerry appeared at a rally in South Carolina which, along with the Western state of Nevada, has become a focal point for Democrats in their battle to pick a presidential candidate in the November election.

"Martin Luther King said that the time is always right to do what is right," Kerry said, referring to the late civil rights leader, as he explained why he decided to back Obama.

"I have the confidence that Barack Obama can be, will be and should be the next president of the United States," he told thousands of cheering, sign-waving Obama supporters at the College of Charleston.

Edwards, who became Kerry's running mate four years ago after failing to win the nomination on his own, said he respected the decision but added in a statement that the election was "about the future, not the past."

The state-by-state process to pick candidates for the November election to succeed President George W. Bush has moved out of the snowy backdrops of New Hampshire and Iowa and on to states across the country ahead of February 5 when 22 states hold nominating contests.
