Photo by Christopher Lee of The New York Times / Michael Bloomberg, former mayor of New York, speaks during a forum sponsored by Everytown for Gun Safety and two of its branches, Moms Demand Action and Students Demand Action, in Des Moines, Iowa, on in August 2019. Bloomberg is expected to enter the Democratic primary race as many voters are still making up their minds on who they prefer.

We've had the baby. So why not the nanny?

Donald Trump has turned the White House — and America — into his crib, wailing and spitting up and throwing things. Republican lawmakers have been consigned to diaper duty. So maybe it's fitting for Mrs. Doubtfire to pop in to lay down the law in this federally funded nursery.

As in love, voters in presidential races often look for the opposite of what they've had. George W. Bush was uninformed and impulsive, so enter Barack Obama. Obama painted cautiously in gray tones, so enter the kaleidoscopic Donald Trump.

Now Trump's vertiginous reign and policies on climate, guns and trade may have inspired the pragmatic Michael Bloomberg to step up as his opposite. Someone from Bloomberg-world told Axios that if the former mayor of New York jumps in, he will spend "whatever it takes" to defeat Trump.

"All across America, people are clutching their Big Gulps," David Axelrod cracked.

It's not a good sign for Democrats — or flagging Joe Biden — that the 77-year-old plutocrat is casting himself as the savior of the party. The trembling Democratic donor class was overjoyed that a Wall Street guy might jump in.

It would be undeniably entertaining to have a stinging face-off between a couple of rich, caustic New Yorkers who have skyscrapers known by their names blocks apart.

"Little Michael," as Trump calls Bloomberg, versus the Big Fraud, as Bloomberg thinks of Trump.

One is a real deal-maker who cares about public policy and one is a fake deal-maker who only cares about himself. One self-made billionaire who's good at business would mock the so-called billionaire and bankruptcy king who needed a constant cash flow from daddy Fred. One is in the media business and one denounces the press as degenerates, lowlifes and enemies of the people. One is a genuine philanthropist and one was just ordered to pay $2 million in damages after admitting money raised by his charitable foundation was used in part for his presidential bid and to settle business debts. One is totally controlling and one is totally out of control. One rants about trans fats and one gorges on them.

Both of these salesmen can be charming or thin-skinned and arrogant. Both have politically fluid histories. Both have their feet to thank for keeping them out of Vietnam; Bloomberg had flat feet and Trump (supposedly) had bone spurs. Both have been accused of having a sexist streak, even though they supported Hillary Clinton at times and have voiced appreciation for smart women. And both men have talked openly about their love of beautiful women.

Trump didn't waste any time trashing a possible new opponent, focusing on looks, as usual. Mr. Rogers said making people feel less than they are was the greatest evil, but for Trump, it's the most fun.

"He doesn't have the magic to do well," the president said of Bloomberg as he left the White House Friday morning for a trip to Georgia, adding, "Little Michael will fail."

Whenever I talked to Bloomberg over the years about running, it was clear he wanted to and felt he would do a great job as Nanny in Chief. But all the polls he commissioned made him think it was not feasible. He didn't want to run against Hillary, and at first he didn't see a path to run this time. But watching Biden implode and Mayor Pete climb and seeing the gazillion-dollar "Medicare for All" plan of Warren — whom Bloomberg thought had a shot as recently as the fall — all combined to tempt him toward a 2020 race.

As The Times' Michael Grynbaum tweeted, slyly summing up the Gotham derby: "How many New York City personalities can one country handle?"

But then, Trump hasn't been too friendly to New York lately. He changed his primary residency to Palm Beach, and on Friday, when he was asked about the fine on his foundation, he barked, "New York is a corrupt state."

And he should know.
