WASHINGTON — Dear Donald,

We’ve known each other a long time, so I think I can be blunt.

You know how you said at campaign rallies that you did not like being identified as a politician?

Don’t worry. No one will ever mistake you for a politician.

After this past week, they won’t even mistake you for a top-notch negotiator.

I was born here. The first image in my memory bank is the Capitol, all lit up at night. And my primary observation about Washington is this: Unless you’re careful, you end up turning into what you started out scorning.

And you, Donald, are getting a reputation as a sucker. And worse, a sucker who is a tool of the D.C. establishment.

Your whole campaign was mocking your rivals and the D.C. elite, jawing about how Americans had turned into losers, with our bad deals and open borders and the Obamacare “disaster.”

You mused that a good role model would be Ronald Reagan. As you saw it, Reagan was a big, good-looking guy with a famous pompadour; he had also been a Democrat and an entertainer. But Reagan had one key quality that you don’t have: He knew what he didn’t know.

You both resembled Macy’s Thanksgiving Day balloons, floating above the nitty-gritty and focusing on a few big thoughts. But President Reagan was confident enough to accept that he needed experts below, deftly maneuvering the strings.

You’re just careering around on your own, crashing into buildings and losing altitude, growling at the cameras and spewing nasty conspiracy theories, instead of offering a sunny smile, bipartisanship, optimism and professionalism.

Instead, you dragged that motley skeleton crew into the White House and let them create a feuding, leaking, belligerent, conspiratorial, sycophantic atmosphere. Instead of a smooth, classy operator like James Baker, you have a Manichaean anarchist in Steve Bannon.

You knew that Paul Ryan’s vaunted reputation as a policy wonk was fake news. Republicans have been running on repealing and replacing Obamacare for years and they never even bothered to come up with a valid alternative.

And neither did you, despite all your promises to replace Obamacare with “something terrific” because you wanted everyone to be covered.

“They tried to sweeten the deal at the end by offering a more expensive bill with fewer health benefits, but alas, it wasn’t enough!” former Obama speechwriter Jon Favreau slyly tweeted.

And you can jump on the phone with The Times’s Maggie Haberman and The Washington Post’s Robert Costa — ignoring that you’ve labeled them the “fake media” — and act like you’re in control. You can say that people should have waited for “Phase 2” and “Phase 3” — whatever they would have been — and that Obamacare is going to explode and that the Democrats are going to get the blame. But it doesn’t work that way. You own it now.

You’re all about flashy marketing so you didn’t notice that the bill was junk, so lame that even Republicans skittered away.

You were humiliated right out of the chute by the establishment guys who hooked you into their agenda — a massive transfer of wealth to rich people — and drew you away from your own.

You got played.

It took W. years to smash everything. You’re way ahead of schedule.

And I can say you’re doing badly, because I’m a columnist, and you’re not. Say hello to everybody, O.K.?

Sincerely, Maureen
