As populists throughout history have found (just Google the Gracchi if you want a two thousand year old example) fighting the established political powers is a perilous task. Far from draining the swamp, Trump is slowly sinking in the mire. Eventually he will be spit out covered in muck and mud and slime. Both political parties and the press want him to fail. His own insiders are stabbing him in tne back with the intensity of Brutus on Caeser. I doubt he has the brains or political savy to survive the daily death by a thousand cuts.
The politicos may fight among themselves. They may squabble over who gets to divide the pie, but no one in Washington is interested in making the pie smaller. Politicians fight too hard, kiss too many asses, debase themselves in their quest for power and money. They will not give it up to an outsider, an interloper, a businessman. Spit.
An outsider and populist never has a chance. When one does, like Hughey Long, he is eliminated. A flawed, shallow, megalomaniac such as Trump is easy pickings. He will destroy himself. He will build his own noose with ill-advised words and 40 character ravings. The press will hoist him on the scaffold and the political parties will nod in assent. Don't fool yourself, Bernie Sanders would have suffered the same fate. The bureaucracy -- the modern Preatorian Guard -- is too entrenched, too corrupt to let anyone endanger the flow of money. I assure you more than one elected official lamented that voters get to, well actually vote, on election day. Many in the press and political class secretly believe they are far more equipped to select the leadership of the country.
Trump is not a danger to The Republic. He is dangerous to the Republic as practiced by the powers in Washington. He will be cowed or destroyed. The socialist Democrats and the socialist-lite Republicans do not really care which path he chooses.
He won't be impeached. That will make the Republicans look bad and hurt heir chances of being in charge of cutting te pie in tne future. But they will work behind the scenes to make sure he does not last more than four years.
