THE GOP'S ANTI-HRC LONG GAME
It's obvious why the Republican Party is fixated on Benghazi, and Hillary Clinton in particular -- it's for this reason:
These are the voters Hillary Clinton showed she could appeal to, and Barack Obama couldn't, in 2008. They could put a lot of states within reach for her that were never in reach for Obama (West Virginia, for instance), and make it relatively easy for her to win states where Democrats usually have to work very hard (e.g., Ohio). Liberals may not fall for the Benghazi witch hunt, but these guys might.
Smearing Hillary in a way these guys find plausible is a small step if Republicans want to be able to beat her, but hey, every little bit counts.
It's hard for us to imagine now that Republicans will ever stop talking about Barack Obama as if he's the most evil human being ever to walk the face of the earth, but, really, they will stop. In the late '90s and 2000, it was impossible to imagine that they'd ever stop describing Bill and Hillary Clinton that way, but they moved on -- to Al Gore and the Dixie Chicks and Dan Rather and Michael Moore and John Kerry and Nancy Pelosi and then, of course, to Obama. They're going to let up a little on Obama after 2014, and Hillary's going to become the most evil person in the world again. They may even decide they kind of like Obama, if they can figure out a way to use that against her. It's going to be bizarre. And it's going to be as ugly as the Obama-hate has been.
