We'll see. My guess is that there are some big bombs that will get dropped between now and the election; like maybe some news on the Clinton Foundation, Uranium One or Seth Rich. For sure POTUS signs the declas EO soon.
A big part of why things are going slowly is obstuction in Congress. How the fuck could POTUS get elected, with a Republican majority, and there's still no wall? It's b.s.; we need to get fresh blood in there to make the big stuff happen.
I imagine the arrests are coming one way or another, but with Congress backing POTUS the job will be a lot easier. But again, they've got to drop some big stuff to make sure they get the desired result; big enough that not even the media can spin it.
