But this senile old kook is?

Via Roll Call:

Republican presidential nominee Donald Trump cannot be trusted with the codes that would unleash the American nuclear arsenal, Vice President Joseph R. Biden, Jr., said Monday.

Biden’s debut on the campaign trail alongside Democratic nominee Hillary Clinton turned into a forceful attack on her GOP opponent, whom the vice president said is already hurting America’s national security.

At the rally in his native Scranton, Pennsylvania, Biden mentioned an individual in his entourage who carries what is known colloquially as the “nuclear football,” a briefcase used to authorize the launch of atomic weapons. Versions of the device go everywhere the president goes, and also accompany the vice president — in case something renders his boss unable to make a launch decision.

“He is not qualified to know the code,” Biden said of Trump. “He cannot be trusted.”
