I agree that Hur’s decision has helped Trump. Whether that was his intention or not, I can’t say, but in all honesty, Hur’s intent isn’t even all that relevant. I can’t imagine him being able to do anything without the approval of higher ups.
My theory is that this was crafted, less to help Trump than to shame Biden into pulling out of the race. Hur was merely the vehicle. I doubt that he would be given the autonomy to write a report that his supervisors didn’t agree with. From the deep state’s point of view, helping Trump was an unfortunate by-product of trying to replace Biden as the Democrat nominee.
FWIW, Hur was Rod Rosenstein’s top aide and protége at the Justice Dept. They called him something like “Mini Rod”. One of Bannon’s guests on War Room mentioned it this past week.
He’s not knowingly going to do anything that would help Trump.
