Another interview "oops" for Gary Johnson.

FOX's Rachel Sutherland reports from Washington:

Libertarian Presidential candidate Gary Johnson has made another gaffe during a broadcast interview. The moment came during on MS-NBC Wednesday, when he was asked to name his favorite world leader:

(Johnson) "I guess I'm having an Aleppo moment, the former President of Mexico... but I'm giving you the whole world, anybody in the world that you like."

Earlier this month, Johnson was ridiculed after being quizzed about the besieged city that's become a focal point of Syria's civil war. Johnson has been polling in the single digits.
