@snood,
No, because the Republicans are still in the middle of the Benghazi smear, as Lash illustrates so often. And when you are trying to smear someone despite them being cleared by multiple investigations, it is extremely embarrassing for people to point out that you have tried this before.
Hence, Lash trying to rewrite history by claiming the Democrats started the idea that Vince Foster was murdered by Hillary, which she feels would render bringing up the quite false Vince Foster anti-Hillary smear of the past out of bounds.
