In an exclusive Hannity interview with brothers George W. and Jeb Bush, the former president weighed in on the grueling nominating process.

They spoke to Sean Hannity following a rally in South Carolina, where George W. Bush said Jeb Bush would be "a strong and steady hand with dealing with the unexpected."

During tonight's interview, the former president expressed confidence in his brother to handle attacks from other candidates, which he said don't anger him, but make him "puzzled sometimes."

“These campaigns need to be tough, because the job’s tough, and we want to see who’s got ability to endure," he said.

"If you wilt on the campaign trail, you'll darn sure wilt in the Oval Office."
