Peter Navarro wasn’t always a sad, whiny insurrectionist. There was a time the former White House trade adviser and Trump henchman was all bright, shiny promise.

In the early 1990s, running as an independent, his good looks drew comparison to Robert Redford.

A few years later, running for Congress as a Democrat, he spoke at the party’s national convention and snagged the endorsement of first lady Hillary Rodham Clinton.

Today, it seems hard to reconcile the nutty former UC Irvine professor who schemed to steal the 2020 election for President Trump with the candidate who inveighed against “fearmongering” politicians and “the extreme right wing of the Republican Party.” Who disparaged Rush Limbaugh and excoriated Pete Wilson’s 1996 presidential bid.

But there is a through-line, say those who have known and observed Navarro for decades: a monumental self-regard, a bottomless hunger for attention — he once showed up for a mayoral campaign event wearing nothing but a Speedo — and an utter lack of grounding principles.

Navarro, 72, has been indicted for refusing to cooperate with the congressional inquiry into the Jan. 6 attack on the Capitol and Trump’s brazen efforts to overturn the will of voters and commandeer the White House.

Investigators would like to know more about Navarro’s interactions with the scheming former president and about Navarro’s so-called Green Bay Sweep, the plan he wrote calling for Vice President Mike Pence to block the Senate from certifying the 2020 election and for Republican-led legislatures to decertify the vote in key battleground states.

Navarro happily blabbed to reporters about his subversive efforts and described them in a book after the election, which the committee noted in the subpoena he chose to ignore.

Lately, however, the armchair mutineer has been reduced to mewling on Fox News and other Trumpaganda media outlets about his treatment by the justice system he sought to subvert — “Who are these people? This is not America” — and grifting appeals for money to help bail him out of his legal jam.

“This is going to cost half a million dollars, from what I’m being told,” he moaned. “I’ll be eating dog food if I stay out of jail.”

Maybe he can enjoy a few square meals wearing prison stripes.

Navarro’s entry into San Diego politics came through his leadership of Prevent Los Angelization Now, an environmentalist group that tapped into the city’s abiding antagonism toward its sprawling northern neighbor. The economics professor parlayed his high profile and preservationist bona fides into a first-place finish in the crowded 1992 mayoral race, then narrowly lost a runoff as developers and other moneyed interests got behind his Republican opponent, Susan Golding.

Navarro passed through a revolving door of party allegiances, alternately identifying himself as Republican, Democrat and independent. Over the course of a decade, he ran a series of increasingly fruitless campaigns for various offices, racking up a total of five losses.

After his failure in electoral politics, Navarro retreated into academia and became a harsh critic of China and its business and trade policies. He wrote several books on the subject — “Death By China” was one of them — and drew the appreciative notice of Trump, who hired Navarro as an economic adviser to his 2016 campaign.

In the White House, Navarro became a leading advocate for tariffs and the trade war Trump waged not only against China but also allies such as Canada and the European Union.

The president and Navarro also seemed to bond over a shared sense of victimhood and their slippery relationship with the truth.

“After losing his 1996 bid for Congress, Navarro wrote a dishy autobiography, “San Diego Confidential,” chock-full of raw commentary on state and local personalities and deeply revealing about its frustrated author. He called himself “the cruelest and meanest son of a bitch who ever ran for public office in San Diego.”

“I still have some principles, but not as many as you might think,” he wrote, “because I don’t have any concern at all about making stuff up about my opponent that isn’t exactly true.”

Navarro may be uncommonly egotistical, desperate for relevance and mercenary in both word and deed. But he shouldn’t be dismissed out of hand.

When Navarro describes himself as ruthless, unscrupulous and a liar, he should be taken at his word.
