Clinton says she's open to being Obama's VP

On a conference call with other New York lawmakers, Clinton, a New York senator, said she was willing to become Obama's vice presidential nominee if it would help Democrats win the White House, according to a participant who spoke on condition of anonymity because this person was not authorized to speak for Clinton.

Clinton's remarks came in response to a question from Democratic Rep. Nydia Velazquez, who said she believed the best way for Obama to win key voting blocs, including Hispanics, would be for him to choose Clinton as his running mate.

"I am open to it," Clinton replied, if it would help the party's prospects in November.

Clinton also told colleagues the delegate math was not there for her to overtake Obama, but that she wanted to take time to determine how to leave the race in a way that would best help Democrats.

"I deserve some time to get this right," she said, even as the other lawmakers forcefully argued for her to press Obama to choose her as his running mate.

Aides to the Illinois senator said he and Clinton had not spoken about the prospects of her joining the ticket.

Obama effectively sewed up the 2,118 delegates needed to win the nomination Tuesday, based on a tally of pledged delegates, superdelegates who have declared their preference, and another 18 superdelegates who have confirmed their intentions to The Associated Press. It also included five delegates Obama was guaranteed as long as he gained 15 percent of the vote in South Dakota and Montana later in the day.
