JUNEAU - U.S. Sen. Lisa Murkowski says she doesn't think Sarah Palin has the leadership qualities to be president, nor the "intellectual curiosity" needed to make good policy.
Murkowski also tells Katie Couric of the "CBS Evening News" she doesn't think Palin enjoyed governing.
Palin, a former vice presidential nominee, resigned midway through her first term as Alaska's governor last year. She's seen as a potential 2012 presidential contender, though the Republican Murkowski has said she wouldn't support a Palin run.
Murkowski and Palin have tangled politically, and Murkowski says the two don't have much of a relationship. However, she says she's still Palin's senator and will "work hard to represent her, too."
