ANALYSIS: TRUE. Trump Faces the Fury of a Scorned Ruling Class: The ‘threat’ that has elites quaking is his serious attempt to curb federal power and cut spending.

A lobbyist friend who visited Capitol Hill recently came away horrified. “I now am ready to believe that the partisanship is so unhinged that it’s a threat to the Republic,” she writes in an email.

This Washington hysteria comes at a time of full employment, booming stocks, relative peace and technological marvels like an electronic robot named Alexa who fetches and plays for you songs of your choice. What’s the fuss about?

We all know the answer: Donald Trump. The Washington body politic has been invaded by an alien presence and, true to the laws of nature, that body is feverishly trying to expel it. These particular laws of nature demand rejection of anything that threatens the livelihoods and prestige of the permanent governing class.

The “threat” that has Washington quaking is the first serious effort in a long time to curb federal regulatory power, wasteful spending, and a propensity to run up mountainous budget deficits and debt. That’s presumably what the voters wanted when they elected Donald Trump. Democrats—accurately regarded as the party of government—seem to fear that Mr. Trump might actually, against all odds, pull it off.

The Washington Post, the New York Times and other apostles of the Democratic Party have apparently set out to prove that despite their shaky business models they can still ignite an anti-Trump bonfire.

So far, what they’ve gotten is people cheering when journalists are shoved to the floor. Plus:

The Washington community knows how to fight back when it feels threatened. Leakers are having a ball, even if it has taken a lot of journalistic imagination to turn the most notorious leaks into “scandals.” Almost everyone in town has a stake in fending off the Trump threat: government workers and the businesses that serve them, public unions, lobbyists and their clients, owners of posh hotels and restaurants that cater to well-heeled visitors seeking government favors, journalists whose prestige derives from the power center they cover, academics who show politicians how to mismanage the economy, real-estate agents feeding on the boom—to name a few. It’s a good living, and few take kindly to a brash outsider who proclaims it is his mission to drain the swamp.

Mr. Trump is on the attack and Washington is fighting back. Is the Republic in danger? Another question is how much danger will it be in if Mr. Trump loses?

I don’t know why these people think that Trump voters will just stay home and sigh if the Establishment wins. It’s likely to be something much uglier. That the Establishment can’t even conceive of other people besides itself deciding to ditch the rules is just one more reason that it’s unfit to govern.
