After a debate like the Republican face off at the Reagan Library Wednesday night, it’s customary for candidates or their surrogates to gather in the spin room to meet reporters and tout their performances. And indeed, everyone gathered in the tightly-packed room — Scott Walker, Mike Huckabee and Ben Carson in person, others represented by campaign aides and supporters — when the debate concluded.

Except Carly Fiorina. In a conspicuous absence, neither Fiorina nor anyone from her campaign showed up after the debate. After it was clear no one was coming, I sent a top aide a note. Was the absence intentional? If so, why?

“Yep,” the aide answered, with a two-word explanation: “Mic drop.”

For those not familiar, the phrase “mic drop” is defined by the Urban Dictionary as “when a performer or speaker intentionally drops/throws the microphone on the floor after an awesome performance” — that is, the performance was so awesome that there is nothing more to say. So Team Fiorina’s post-debate silence was a sure sign the candidate was happy.
