Not sure if indictments of the higher echelons (e.g. Obama, Hillary, Brennan, etc.) will come out before elections, but certain things must. For one thing - information about voter fraud needs to come out in enough time to get national voter I.D. passed. Also, something big enough to change the make up of Congress so that voter I.D. can pass.
For another thing, enough damaging info on whoever ends up being their nominee needs to come out to ensure a Trump victory, whether he/she is indicted or not.
Agree in general, but I’m guessing no arrests, etc. Until after the election. Arrests orci indictments could backfire and there’s no time left to get convictions.
