The policy of how the intelligence agencies deal with politically charged information is to not interfere with elections. Comey's delivery of the letter about email being found was astonishing because he was acting in a way counter to the long-standing policy about dropping sensitive and uncorroborated information into the election news cycle. His successive letter was too little too late to counter the damage of his act. The fact that the Trump stuff wasn't dropped into the news cycle because it hadn't been corroborated because it hadn't been proved is the way they were supposed to behave. Clearly it was leaked by people who couldn't stand that this stayed hidden, but it won't affect the Trump/Clinton election, even though she resoundingly won the popular vote. Now this may contribute to a Pence presidency - and while Trump sways in the wind, influenced by whoever last spoke to him, Pence is a religious zealot who would knock society back to the dark ages with his views on women's rights, the rights of workers, access to health care, the right to get birth control and abortion on demand, and many other issues that he has diligently fought for years. He is the awful underbelly of the Trump administration.
