Trump's loyalists have been mocking of Mueller and dismissive of his impact -- "he's got nothing" they've been claiming -- but it looks like they're wrong again, as they've been about so much. 
Donny will lead them in the cries of "witch hunt" (as Nixon led his gang in 1973-74) but here comes justice, slow but sure. Will he in his desperation move to shut down the investigation, and with GOP acquiescence will he succeed -- great drama, and perhaps a coup of sorts. Or will his voting base, having somehow seen him as a saviour and even a revolutionary, be charged with collective stupidity.
