Republican vice presidential candidate Sarah Palin says she thinks Democratic presidential candidate Barack Obama regrets not making Hillary Clinton his running mate.

The state police officer at the heart of a legislative investigation into whether Republican vice presidential nominee Sarah Palin abused her power as governor of Alaska says he has not been contacted by the man overseeing the inquiry.

A man who rambled and said ‘‘stuff that made no sense’’ stabbed four children at an elementary school in Alaska before he was subdued by police, authorities and witnesses said.
