Can This Political Career Be Saved?

Or, more important, should it?

The second-ranking Senate Republican offered no support Sunday for embattled U.S. Sen. John Ensign, facing renewed criticism over an extramarital affair with an aide and the actions he took on behalf of her husband.

Asked on CNN's "State of the Union" if Ensign can serve effectively or should step down, U.S. Sen. Jon Kyl, R-Ariz., did not address his colleague's future and said he would await a Senate Ethics Committee investigation.

No presidential aspirations for you, John.
