Cain gets stumped badly by question at Cain-Gingrich debate

During the Herman Cain-Newt Gingrich debate Saturday evening, the former CEO of Godfather's Pizza had another not-so-presidential moment in a rocky week for him.

When asked by Americans for Prosperity Texas chairman Ben Streusand on whether he would favor either a "defined benefit plan" or "premium support" for Medicare, Cain's confusion to the question was apparent. 

After a long ponder, the Republican frontrunner decided to pass the question to his counterpart on stage. "You go first Newt," he said.
