ABC News has revealed the RNC had prepared an ad on Benghazi in the final days of the presidential election. 

However, the ad never aired because of objections from the Romney campaign who thought the ad would detract from their message on the economy. 

Having now viewed the ad, it probably would have taken focus off the economy.

But so what.

Are you trying to win an election or not?

If you are and especially if you trying to unseat an incumbent, you do everything possible to germinate the seeds of doubt and undermine the credibility of your opponent. This ad could have achieved those objectives. The ad begins with a replay of Hillary Clinton’s 3 a.m. ad against Barack Obama before panning to video of the U.S. Consulate in Benghazi in flames. The following copy is accompanied by repeated telephone rings while the last two lines are accompanied by a busy signal:

The Call Came on September 11, 2012.

Security Requests Denied.

Four Americans Dead.

And An Administration Whose Story is Still Changing.

The Call Came.

Americans Deserve Answers.

O.K., there’s no guarantee that airing this ad would have won Romney the election. It might have been too late by then. But at that stage, Romney had nothing to lose by letting the ad air. It could have very well changed the narrative on Benghazi. But, of course, now we will never know.

On the other hand, should Hillary run in 2016, her Republican opponent cannot let her off the hook for Benghazi.
