Now look at this closing paragraph of Comey's letter:
Although the FBI cannot yet assess whether or not this material may be significant, and I cannot predict how long it will take us to complete this additional work, I believe it is important to update your Committees about our efforts in light of my previous testimony.
In other words, there's no indication at all in that letter that anything significant has been found. That doesn't change the fact that this is going to hurt Clinton. But it is the truth of the matter. There is absolutely nothing about what Comey said in the letter to indicate that there is any information that would change his previous conclusion.
All that's happened is that they noted that Huma Abedin's used that laptop to engage in e mail exchanges with Clinton. That's it. What's probably going to happen is that the FBI is going to end up saying that nothing has changed with regard to its conclusions. But the fact that it happened 11 days before an election when there is no time to sort things out is going to hurt Clinton.
Hopefully she'll still win so we won't have a dangerously mentally ill person in the President's position.
