Carson, who has struggled to grasp foreign policy intricacies on the campaign trail, posted a peculiar video Tuesday morning saying "I sure hope that we are going to get a lot of questions about foreign affairs and national defense."
"If so, slam dunk," Carson said.
During the campaign, Carson has struggled to articulate a clear way to defeat the Islamic State and he accused China of being involved in the civil war in Syria.
Carson's own advisers have gone on record criticizing their candidate's lack of mastery of world affairs. Duane Clarridge– a former CIA spook turned self-financed spy– told the New York Times that Carson was in dire need of a weekly briefing.
The video suggests Carson is keenly aware that his support is slipping and the debate stage Tuesday night may be his last chance to prove to voters he's got foreign policy under control.
As Carson says in his video, "It should be fun."
