Here's an Idea, Mr. President . . .

Sometime in 2011, I got a call from Donald Trump. He said he was thinking of running for president and wanted to know what I thought of the idea. I'm guessing he also called a million other journalists, but I had reported a story on his golf course in Scotland (for HBO's Real Sports) and after it aired he told someone, "Bernie didn't do me any favors, but he was fair." Maybe that's why he called. Who knows?

Anyway, I told him that because I'm a journalist I don't give advice to people thinking of running for president (or any other office). We chatted for a few more moments and that was the end of it.

If he asked my advice now - he won't! - I'd relent and tell him that since that conversation he has become the most disruptive president at least in our modern era and probably in all of our American history.

I'd tell him his war with the press is especially troubling. He says his critics in the media peddle "fake news." Not really. A lot of them, though, do peddle "biased news." They hate him and it comes out in their decisions about what to cover and how to cover it (though he gives them plenty of ammunition).

But I'd tell him that there's a better way to deal with the press than waging non-stop war against journalists.

First, no more tweets about Mika "bleeding badly from a face-lift" she says she never had. And no more videos of businessman Donald Trump body slamming a guy with the CNN logo imposed on his face.

Someone needs to remind the president that he holds the same office as George Washington and Abraham Lincoln. A little dignity is in order.

Let's acknowledge that many of the president's most loyal fans love it when he attacks the press, when he fights fire with fire, to use the term his press person used at a recent briefing. But appealing to the base isn't getting him anywhere.

Mr. Trump won the election with 46 percent of the vote. Now his approval numbers are in the 30s, which means that even a lot of people who voted for him - the ones who weren't crazy about him but who couldn't bring themselves to vote for Hillary - even those people are abandoning ship.

The 25 or 30 percent who think he's a messiah are not the kind of friends he needs right now. Yes, they give him the adulation he craves. But they'll be there for him no matter what. And if they're all he's got he can forget about turning his vision of making America great again into a political reality. If the pols in Washington aren't afraid of him - and they won't be if his numbers stay in the 30s - they won't put their necks on the line to support his agenda.

So here's an idea for the president, an idea for a national TV address that his loyal fans might not embrace - who cares? - but just might win over moderates who aren't in the Never Trump crowd. Imagine if he said something like this:

"My fellow Americans, my focus tonight is on one of the most important institutions in our great country: the news media.

"We all know we can't have a free country without a free press. But neither can we have a free country without a fair press.

"Let me be clear: Journalists not only have the right, but they have an obligation to hold me accountable for my actions. With that, I have no problem.

"But let's not pretend that journalists don't have an agenda, one that goes beyond simply telling the truth. And just as I've been charged with trying to delegitimize the media, too many in the media have been trying from Day One to delegitimize my presidency.

"Joe Scarborough has called me a 'schmuck' on national television. He has said I remind him of his mother who has dementia. Mika Brzezinski has said I don't love my country. Others have called me a thug, a pig, Hitler and a whole bunch of other less-than-flattering names.

"Tonight I acknowledge that my tweets in response too often have been needlessly vindictive - and counterproductive. But journalists "haven't merely defended their reporting, they've doubled down on attacking" me, as a writer in National Review put it.

"So, as Monty Hall used to say, Let's make a deal: I will continue to point out what I believe is false news about my administration and me. But I will stop the personal attacks on members of the press.

"But it wouldn't hurt if journalists showed some contrition, too. It wouldn't be so terrible if reporters acknowledged that because they think I'm "unfit to be president," they also think it's okay to inject bias and malice into their stories without fear of consequence.

"Someone has to put an end to this. Someone has to say 'Enough.' I'm saying it right here, right now."

If he delivered that speech, his poll numbers would head northward - regardless of how his critics in the media reacted.

But no, I'm not Pollyanna. I understand that Donald Trump may be incapable of not fighting back, often in childish ways.

And too many journalists see themselves on a noble mission to save the nation from this president - especially now that he tweeted about Mika's bloody face and circulated that video of him beating up on the guy with the CNN head.

The more Mr. Trump attacks journalists the more they attack him. And the more they attack him the more he attacks them. He won't stop unless they stop first. And they won't stop unless he does, if then. This reminds of me third grade: You started first. No, you started first.
