If Hillary is seriously tainted by Benghazi-gate, or for some other reason is not a viable nominee in 2016, whom do the 'Rats have to offer? Michelle Obama? Joe Biden? Cuomo? Fauxcahontas? They don't have a very strong bench--the primaries could be another case of "the Seven Dwarfs" (except that the MSM would try to turn the survivor into a combination of FDR and JFK).
The news media will bring forth some unknown person and annoint him/her as the “one” just like they did with Obama, because they knew Hillary couldn’t win.
Everyone keeps talking about Hillary being the strong candidate for the next Dem Nominee, but I see no evidence that she actually improved her likability or her ability to be elected. Too many people just don’t like her.
