Clinton defies calls to quit race

INDIANAPOLIS, May 1 (UPI) -- Sen. Hillary Clinton said Thursday those who say she should get out of the presidential race "don't understand politics or history."

Campaigning in Indianapolis on the same day Joe Andrew, a former head of the Democratic National Committee and an Indiana superdelegate, switched his support from Clinton to Sen. Barack Obama, D-Ill., Clinton countered Andrew's assertion that continuing to support her was bad for the Democratic Party, ABC reported.

Interviewed for ABC's "Nightline," Clinton, D-N.Y., said, "I think this has been good for the Democratic Party."

When asked if she would pull out of the race if she didn't win the Indiana primary, Clinton replied, "I'm not going to pledge to do anything. I'm going to just keep getting up every single day and going out there.

"I think that this is such a close election, why would any of us think that it shouldn't go to the end? We've got a process. The rules are it goes all the way into June. Let's follow the rules and get to those June contests and see where we are."

Andrew, named DNC chair when Clinton's husband was president, wrote a letter to other superdelegates, urging them to commit to Obama, The Hill reported Thursday.

"The battle should not be amongst ourselves," Andrew wrote. "We should focus our efforts on those who are truly on the opposite side: those who want to continue the failed policies of the last eight years."
