No, I believe politics should not drive decisions made by the FBI. Unfortunately, when you make a decision during an election year you will influence the elections for one party or another regardless. At that point, I believe it's the duty of the FBI to just tell the truth. In the case of Clinton, Comey first came out saying that Clinton was in the clear. The problem was. Potential additional evidence was discovered after that statement. Comey could sit on it, in which case, the GOP would blame him for trying to cover up evidence if it leaked. Which it would surely do. Or he could immediately release it. In an attempt to cut off the accusation. And try to expedite the evaluation of the potential evidence. Now, I think there is nothing wrong with making decisions based on what you consider the best of 2 shitty options.
