Where are the GOP candidates on the debt ceiling???

I was listening to some conservative economists on the radio and they were voicing their disappointment that none of the GOP presidential candidates have said diddly squat about what they think should be done about the debt ceiling.  Bachman doesn’t want the debt ceiling raised at all, showing her ignorance of economic reality.  None of them have said what they think SHOULD be done.  So much for leadership.  How am I supposed to decide if there is a viable alternative to Obama if I don’t know what they will do? I guess they are trying to be the anonymous GOP candidate that is the only one beating Obama in the polls.
