NEW YORK • The former New Jersey governor and onetime Republican presidential candidate denounced “conspiracy theorists” during a September appearance at the Ronald Reagan Library in California.

He followed up with a speech this month to influential Republicans in Las Vegas, warning that the party will only succeed if it offers a “plan for tomorrow, not a grievance about yesterday.”

In between, he’s been interviewed by everyone from Laura Ingraham on Fox News to David Axelrod, a former adviser to President Barack Obama, on CNN.

On its face, Christie’s publicity campaign is in service of “Republican Rescue,” his new book that offers a simple prescription for his party: stop talking nonsense about 2020 and focus on the future — or keep losing elections. But the frenzied pace of his appearances and the increasingly obvious jabs at Donald Trump suggest Christie is plotting a political comeback with the 2024 campaign in mind.

In a recent interview, Christie

said he hadn’t made a decision yet about his political future and wouldn’t until after next year’s elections. But he was blunt in saying he would run if he believes he can be elected.

“If I see a pathway to winning, I’ll run,” he said. “And I feel like I have the skills and the talent and the ability to be able to make a difference in our party and in the country. And I’m certainly, at 59 years old, not ready to retire. But I’m not going to do it if I don’t see a pathway to winning. So that’s why I’m not making any decision now.”

One of the biggest questions that hangs over the 2024 campaign is whether Trump will run again. If the former president does, polls suggest he would easily clinch the nomination.

But until that’s decided, Christie is testing the openness of GOP voters to someone who largely supports Trump’s record but dismisses Trump’s lies that the last election was stolen.

It’s an approach that pits him against other Republicans who may run in 2024, including Rep. Liz Cheney of Wyoming and Maryland Gov. Larry Hogan, who have taken high-profile stands against Trump.

Florida Gov. Ron Desantis and Mike Pompeo, Trump’s former secretary of state, have pitched themselves as fierce Trump loyalists. Former Vice President Mike Pence has tried to find something of a middle ground, highlighting his work alongside Trump but noting the two hold different views about the circumstances surrounding the Jan. 6 insurrection at the U.S. Capitol.

As candidates largely break into pro- and anti-trump camps, “there is a thing to being in a unique lane that does in fact endorse some of President Trump’s policies but at the same time doesn’t hesitate to criticize where Christie would disagree with him,” said longtime GOP pollster Adam Geller. He worked on Christie’s two winning New Jersey gubernatorial campaigns as well as Christie’s 2016 presidential bid, followed by Trump’s.
