There has been alarmingly little discussion about foreign policy in the GOP race for president, so why not book a second debate in four days on the least watched night of television viewing of the week?

That's what happened Saturday night, as CBS News & the National Journal teamed up for a 90-minute debate from South Carolina, an hour of which was aired live on the broadcast network, the remaining time only available online.

It definitely had its entertaining moments, not least of which was holding one's breath every time Herman Cain was asked a question, which was often, being that the former Godfather's CEO is currently the co-front runner in the contest.

How'd he fare? Well, one anonymous Democrat told the National Journal that "It was a deer in the headlights performance."
