The way things are going, Donald Trump is going to have to get a restraining order against Elizabeth Warren.

The senior senator from Massachusetts, with her extreme and escalating rhetoric against Trump, is acting as though she’s unhinged.

It is either a restraining order or a call in to Attorney General Maura Healey’s new hate crime hotline that was set up following Trump’s election to report acts of intimidation or harassment.

It is not often that a U.S. senator promises to stalk a president, but that is what Warren has vowed to do. Stalking is scary. This lady is scary.

And Warren’s threat has nothing to do with any important Massachusetts issue — like federal support for the Green Line Extension into Somerville and Medford, for instance — but concerns the hiring of lobbyists and Wall Street insiders on Trump’s transition team.

Warren said she asked Trump to remove those insiders from his transition team, or there will be trouble.

She said to the new president, “Let me be clear. If you refuse, I will oppose you, every step of the way, for the next four years. I will track your every move, and I will remind Americans, every day, of the actions you take that fail them. And I will not be the only one watching. The millions of Americans who voted for you — and the millions who didn’t — will all be watching you.”

It is not known whether Trump, now quaking in his boots, called Healey’s hate hotline to report the threat, but he should.

Healey said she set up the hotline in response to reports that people — Muslims, gays, immigrants and women — “had been subjected to conduct that imperils safety and civil rights,” as a result of Trump’s victory, a victory that caught the liberal establishment by surprise.

Although men (like Trump) were not mentioned, it is presumed they are covered as well. But you never know. Healey called Trump “a miserable person” to begin with — not a miserable “man,” but a miserable “person.” So Trump, being merely a man, may not qualify, and that is perhaps a reason he has yet to report the threat.

Still, he should try, especially now that he is no longer Campaign Trump, but President-elect Trump.

He could have called and left a message saying, “By the way, have Elizabeth call me so we can talk about the billions of dollars Massachusetts wants earmarked for the Green Line Expansion.”

One would think that by now, after the election dust has settled, that Warren would moderate her words. Instead, shaking her head, waving her arms and pointing her finger, she has intensified her vitriol.

It seems that Warren, in her partisan zeal, simply cannot get over Trump’s victory, despite the fact that the man she called “a thin-skinned, racist, sexist bully” will now decide how many billions of taxpayer dollars — if any — will be forwarded to Massachusetts.

There would be some hope if Warren, like Mitt Romney, could make amends. No Republican was more critical of Trump than Romney, but the former Massachusetts governor did meet with Trump.

Republican Gov. Charlie Baker should do the same because, if the state is to rely on Warren to seek its fair share of federal funds from the Trump administration, then Baker, like Romney, must make amends. Otherwise it will be a long two years for Baker before he seeks re-election in 2018.

And Eddie Markey, the state’s other senator, and another Trump critic, appears to have gone missing since the election. But no matter, Markey, who lives in Maryland, is such a stranger that he needs a visitors pass to get back into Massachusetts anyway.

Here is the situation in a nutshell. While all the political leaders in the state support the costly extension of the Green Line into Somerville and Medford, federal taxpayer money is needed to build it.

Who is going to secure those funds?

In addition, Trump will be made aware of the fact — if he doesn’t know already — that Boston, Somerville and Cambridge, where the extension will start at Lechmere Station, are the Bermuda Triangle of sanctuary cities.

All three cities have promised to remain sanctuary cities, despite Trump’s promise to withhold federal funds from sanctuary cities, as well as his vow to rid the country of illegal immigrants who have committed serious crimes.

It would be a shame if the criminals in the illegal immigrant community are denied access to public transportation within the Bermuda Triangle of sanctuary cities. Elizabeth Warren should do something about it.
