Sen. Ted Cruz was one of three senators to vote against the confirmation of Sen. John Kerry as Secretary of State today. In a statement, Cruz said he opposed Kerry because of his “less-than-vigorous” defense of U.S. security interests.

Paul Begala was among the first to question Cruz’ right to vote against someone he didn’t think was right for the job by going after Cruz’ status as a non-veteran. Begala flubbed the video game reference, though.

So, were only senators who have served allowed to vote on the confirmation? Or were non-veterans allowed to vote “yes,” but not “no”? How does this work, exactly?

About those medals…
