The 'rub'...
Taking out the quasi ethical ("DC" ethics) Mueller would leave us with his merry band of Clinton loyalists ready for blood - - a bunch lacking in Mueller's DC ethics - (one step better than 'no ethics') while holding an irrationally strong tribal hatred for Trump...
Trump's got to figure this one out...
Ramping up the heat on Clinton crimes might be the path... kind of a mutually assure destruction gambit... Liz, is the DNC/ Muslim brothers/money laundering and espionage enough?
Investigate Mueller and his merry band of Clinton loyalists, just to make sure they’re not guilty of something. That’ll keep them busy, maybe busy enough to slow them down some.
