(CNN) - In a new interview, Hillary Clinton again seems to raise the prospect that "pledged" delegates – those awarded based on election results – might still be considered up for grabs..
"There are elected delegates, caucus delegates and superdelegates, all for different reasons, and they're all equal in their ability to cast their vote for whomever they choose," she told Newsweek in an interview published Sunday. "Even elected and caucus delegates are not required to stay with whomever they are pledged to."
After a similar reference earlier this year drew sharp criticism from Obama supporters, the Clinton campaign said that they had not been planning to try to actively convince the Illinois senator's pledged delegates to switch sides, and would not do so in the future.
Barack Obama leads Clinton among all Democratic delegates, 1,527 to 1,428, in the latest CNN count. Among pledged delegates, Obama leads Clinton 1,328 to 1,190.
