It is not over. I fully expect that after the midterms, mueller will make his move. It is even possible that if the midterms start looking really bad for dems, he may pull the nuclear option. That would be making charges against Trump before the midterms.
Yep, either it will be an October surprise of outlandish claims or all this SC stuff has exposed the level of importance they really believe it has, which is probably very little at this point.
