Why is official Washington so determined to rid itself of Donald Trump? The usual answers focus on the country’s ideological divisions, now calcified in the parties, and Trump’s polarizing personality. Democrats of all stripes truly loathe him. All true, but those are only part of the answer.
There is a deeper reason that helps explain both the origins of the impeachment articles and the larger movement to remove Trump. The key is that Trump not only ran against Washington’s entrenched power, he is actually delivering on that promise. Nothing is more dangerous to the Beltway’s power and profits, to its most powerful actors and the foot soldiers behind them. Those endangered interests are the essential backdrop to the House impeachment and Senate trial.
Trump not only ran against the capital’s lobbyists, lawyers, and bureaucrats, he has avoided capture by them since taking office. Instead of making his peace with traditional Republican constituencies, such as the U.S. Chamber of Commerce, he has shut them out. He pays little attention to familiar Republican think tanks. Instead of deferring to state party leaders, he stepped into the primaries, backed his own candidates (often underdogs), and showed it was fatal for Republicans to oppose him. Back in Washington, the Democrats shut out Trump, deciding from the outset to block as many of his Cabinet and judicial appointments as they could. The result is that Trump firmly controls his own party and is uniformly opposed by Democrats, who are otherwise fractured by ideology and age.
