L.A. mayoral hopeful Spencer Pratt is making a big splash, but can he swim?

Spencer Pratt, please give me a call.

We should talk.

You say you want to be mayor of Los Angeles, but do you really?

I know that being a candidate has rescued you from anonymity after your career in reality TV went off a cliff. You’ve got CEOs backing you, and fans raving, and you’ve managed to milk social media attention.

But at some point you might have to answer questions from the reporters you’ve been avoiding.

And if you win, you’re going to have to drive to City Hall five, six, seven days a week, and I don’t know if you saw my column a few weeks ago, but the fountain on the south lawn hasn’t worked in about 60 years. If you get elected, you better put a wrench in your lunch box, because nobody has figured out how to fix it.

So that’s the reality, pretty much. And the unions will want what they want, and the socialists on the City Council will be lying in wait, especially after President Trump blew you a cross-country air kiss and certified your MAGA credentials.

More than 30,000 people are waiting for their broken sidewalks to get fixed (I’m not exaggerating) but there’s no money, and if you hire several thousand more police officers as you’ve pledged, the city would be bankrupt for the next decade or so and you’d need to take out a loan to buy a doughnut.

So call me, like I say, because I think there’s still time to change your mind.

If you choose to proceed, and if you actually win, it might feel like you’re in a sequel to that reality show you did called “I’m a Celebrity … Get Me Out of Here,” and you may end up praying the show gets canceled. The mayor’s hours are long, and everywhere you go, someone will want you to fix this problem or that, and as you wander the halls of power you’ll think back on your campaign pledges and hear the constant echo of a line from H.L. Mencken:

“For every complex problem there is an answer that is clear, simple, and wrong.”

Can I confess something?

I’m feeling guilty about all of this.

Not to sound presumptuous, but I feel partly responsible for the fact that you’re in contention for the job.

Like you, I’ve been calling out issues with the management of L.A., and I’ve been doing it for years. But I had the good sense not to run for mayor.

Why’s that?

Because unlike you, I know the fixes aren’t as easy as we’d like them to be.

When Karen Bass was running the first time, I had a long talk with her about her homelessness plan, among other things. At the end of the day, she asked for my input.

I reminded her that as much as people would like for the city’s top elected official to immediately clear the streets, a mayor is limited by shared power with the City Council.

By drug epidemics and untreated mental illness that are largely under county authority.

By uncertain funding from the nation’s capital.

By global forces that transformed the economy and created staggering levels of inequality that are made all the worse by the high cost of housing.

Bass was aware of all that, but said that having worked in Sacramento and D.C., and having built relationships with county supervisors, she’d be able to build better systems and get better outcomes.

So how has she done?

Not great. And then there’s the fire.

As I’ve said before, leaving the country despite forecasts of elevated wildfire risk was probably the worst mistake of her political career.

I don’t need to remind you of that. Having lost your house in the Palisades, you know that Bass badly underreacted, then stumbled on the rebuilding, and then had a hand in downplaying the Fire Department’s failure to adequately deploy and extinguish the fire that became an inferno.

To summarize, she’s left herself wide open to a challenge.

And she probably can’t believe how lucky she is that you might be her November competition, if the two of you bounce out Councilmember Nithya Raman and the other candidates in the June 2 primary.

I don’t hold it against you that you haven’t worked in government or politics before. These days, a lot of voters prefer outsiders. But it might have helped if you’d done something of purpose at some point in your life, like run a successful business or volunteer at a food bank. Were you junior high class president, or were you in the Boy Scouts? Anything could help.

Not that being the boyfriend and later the husband of someone on an MTV reality show called “The Hills,” which chronicled the work of a woman who went from “Laguna Beach: The Real Orange County” to an internship at Teen Vogue, can’t prepare a young man for statesmanship.

In this culture, you could ride that all the way to the White House.

But the flimsy resume could explain, Spencer, why you’ve been taking so many social media-fueled potshots at Bass without offering anything of substance.

Let’s arrest drug zombies.

OK, then what?

I’d advise you to study the primer by my colleagues Doug Smith and Andrew Khouri on what you can and can’t do about homelessness as a mayor in L.A. Clearly, you’ve got a lot of boning up to do. In fact, I’m reminded of a line by a Philadelphia columnist years ago, when he said of a politician who wasn’t up to the job: He’s been standing in shallow water for so long, he doesn’t realize he can’t swim.

If I were you, I’d consider the fact that President Trump made the mistake of promising easy fixes. He was going to deliver a massive infrastructure program. He was going to deliver healthcare reform that was better and cheaper for everyone. He was going to lower consumer prices on Day One, and here we are, with millions of people wondering how they’re going to pay their bills while Trump rigs it so he doesn’t have to pay the IRS.

All that being said, I’m glad you decided to run, because elected officials need constant reminders that their jobs are not secure, even when the challengers are way in over their heads. I’d almost like to see you win, because that’s one reality show I’d be sure to watch.

And I say this despite the fact that you once told your talk show buddy Alex Jones — who insisted that 9/11 was an inside job and that the Sandy Hook massacre of 20 children was a hoax — that melting ice caps are overrated. Or, as you explained it to Jones, “we’ve all seen footage of the polar bears swimming to new pieces of ice.”

When the general election rolls around, and the ice begins to break, will you know how to swim?
