Let me take a moment here to point out that in addition to the email issues addressed by James Comey yesterday, Mrs. Clinton has to still deal with the ongoing (and unmentioned) FBI investigation of the Clinton Foundation for corruption while she was the sitting Secretary of State. If you read his note carefully, you'll see that the scope of his statement does not address any questions regarding the Clinton Foundation, which is an investigation separate from the one concerning the bathroom server.
This won't keep her from getting elected, but it will be back to haunt her unless she decides to carry out her own "Saturday Night Massacre" along the way. You'll see many more references to Watergate in coming months and years to draw parallels to what you're seeing in real time.
Vault this.
