Backwards logic.

While the accusations against Susan Rice are beginning to simmer down, one would expect the opposition to her nomination (which has not been made yet) would take a calmer tone.  Rep. Jeff Duncan has decided to double down, instead, claiming that Rice has been "tainted" by this whole Benghazi affair.  Of course she has, because your party tainted her.  It's a little like throwing a pile of shit at someone and then complaining that he stinks of shit.

This is a brilliant tactic--1. Question the credibility of your opponent; 2. Once her credibility has been restored, argue that it doesn't matter because her reputation has been smeared (with no recognition that you are the one who smeared her). 

(This is not an endorsement of Susan Rice for Secretary of State).
