SACRAMENTO —  OK, I admit it. I’m biased. I hate it when an opportunistic politician capitalizes on other people’s miseries and tries to score political points.

I’m especially biased when it’s a president-elect who shoots off his mouth without regard for facts and blames a governor for fire hydrants running dry.

Not that Democrat Gavin Newsom is a perfect governor. But his California water policies had no more to do with Pacific Palisades hydrants drying up during a firestorm than did Republican Donald Trump’s turning on sprinklers at his golf course.

News reporters shouldn’t allow personal biases to seep into their stories, as Los Angeles Times owner Patrick Soon-Shiong has reminded us. Reporters have long strived to not do so and mostly succeeded. But I’m not a reporter. I’m a columnist who analyzes and opines. And yes, I’m biased — but on issues, not politics.

It has always been my view that liberals, moderates and conservatives all have good and bad ideas. Neither party has a monopoly on truth and justice — except in relating to Trump.

I wanted to give Trump the benefit of the doubt and watch whether he really intended — as promised — to be a president for all Americans. But the guy just can’t help himself.

When Trump blamed Newsom for water hydrants going dry as Pacific Palisades burned, it wasn’t something people should dismiss as just another Trumpism.

Here was a president-elect mouthing off and showing his ignorance in a barrage of vindictiveness and insensitivity as thousands of people fled for their lives and hundreds of homes blazed into ashes.

Yes, I’m biased against anyone who’s that uncivil, especially when he disrespects facts or — worse — is a pathological liar.

So, let’s recap what Trump did.

As scores of hydrants went dry while fire crews battled flames in Pacific Palisades, the president-elect instinctively went on social media to point the finger at his left coast political adversary, the Democrat he tastelessly derides as Gov. “Newscum.”

“Governor Gavin Newscum refused to sign the water restoration declaration put before him that would have allowed millions of gallons of water from excess rain and snow melt from the north to flow daily into many parts of California, including the parts that are currently burning in a virtually apocalyptic way,” Trump asserted.

“He wanted to protect an essentially worthless fish called a smelt … but didn’t care about the people of California. Now the ultimate price is being paid.

“I will demand that this incompetent governor allow beautiful, clean, fresh water to flow into California. He is the blame for this. On top of it all, no water for fire hydrants, not firefighting planes. A true disaster.”

True drivel, putting it politely.

First, what was this so-called water restoration declaration?

“There’s no such document,” responded Izzy Gardon, Newsom’s communications director. “That is pure fiction.”

Trump probably was referring to his policy differences with Newsom on water exports from the Sacramento-San Joaquin River Delta to farmlands in the San Joaquin Valley. In his first presidency, Trump wanted to drain more fresh water from the delta for irrigation in the valley. But both Govs. Jerry Brown and Newsom took a more centrist approach, striving for a balance between farms and fish.

Second, it’s not the demise of the tiny smelt — the Republicans’ favorite target — that’s so concerning to many conservationists. It’s the rapid decline of iconic salmon that previously provided world-class recreational angling in the delta and fed a healthy commercial fishery on the coast. Salmon fishing seasons have been closed recently to save what’s left of the fish.

Third, despite Trump’s claptrap, plenty of fresh delta water is being pumped south to fill fire hydrants and the tanks of firefighting aircraft. Hundreds of millions of gallons of water flow daily down the California Aqueduct. Major Southland reservoirs are at historically high levels. Anyway, much of L.A.’s water doesn’t even come from the Delta. It flows from the Owens Valley and the Colorado River.

Fourth, the hydrants went dry simply because there were too many fires to fight, the Los Angeles Department of Water and Power explained. Storage tanks went dry.

“We pushed the system to the extreme,” Janisse Quinones, DWP chief executive and chief engineer, said. “Four times the normal demand was seen for 15 hours straight.”

Yes, I’m biased against politicians who make up stuff.

But you’ve got to listen to Trump because he could follow through on what he’s bellowing about.

For example, Trump vowed during the presidential campaign to deny Newsom federal money to fight wildfires unless the governor diverted more water to farms.

That apparently wasn’t an idle threat.

Trump initially refused to approve federal wildfire aid in 2018 until a staffer pointed out that Orange County, a beneficiary, was home to many voters who supported him, Politico reported. And in 2020, the Federal Emergency Management Agency rejected an aid request during several California wildfires until Republicans appealed to Trump.

So, what’s Trump going to be like when he actually becomes president again and is wielding real power, not just running off at the mouth?

Will he try to annex Greenland? Seize the Panama Canal? When a reporter asked him whether he’d commit to not using “military or economic coercion” to achieve these goals, he immediately answered: “No.”

Will he keep calling Canada our “51st state?”

Yep. I’m biased against such immature and dangerous political leaders.
