INDIANAPOLIS, May 6 (Reuters) - Hillary Clinton on Tuesday vowed to continue her quest for the Democratic presidential nomination after a projected win in Indiana kept her hopes of beating front-runner Barack Obama alive.

The New York senator, flanked by her husband, former President Bill Clinton, and daughter Chelsea, said she would support whomever wins the nomination, while vowing to press on after a definitive loss to the Illinois senator in North Carolina.

"I can assure you, as I have said on many occasions, that no matter what happens, I will work for the nominee of the Democratic Party, because we must win in November," she said.

The former first lady sounded a victory note despite signs that her win in Indiana would be narrow.

"Tonight it's your victory," she told a cheering crowd after CBS News projected that she had won the state's primary.

"Tonight we've come from behind. We've broken the tie and thanks to you, it's full speed on to the White House," she said.

Clinton turned her attention to the remaining contests.
