Republican presidential candidate Vivek Ramaswamy has canceled all spending on TV ads with just weeks until the first caucus in Iowa and primary in New Hampshire.

The exit from the TV ad wars doesn’t bode well for a presidential campaign, but Mr. Ramaswamy said he was not dropping out of the race.

The biotech entrepreneur said his campaign was merely switching gears to spend more energy and money on other efforts.

Still, former President Donald Trump took the announcement as a sign he would soon get an endorsement from Mr. Ramaswamy.

“He will, I am sure, Endorse me. But Vivek is a good man, and is not done yet!” Mr. Trump, the prohibitive favorite in the GOP presidential race, wrote on Truth Social.

“We are focused on bringing out the voters we’ve identified — best way to reach them is using addressable advertising, mail, text, live calls, and doors to communicate with our voters on Vivek’s vision for America, making their plan to caucus and turning them out,” Tricia McLaughlin, the campaign spokeswoman, told NBC News Tuesday.

“As you know, this isn’t what most campaigns look like. We have intentionally structured this way so that we have the ability to be nimble and hyper-targeted in our ad spending,” she said.

Mr. Ramaswamy’s campaign announced in November that it planned to spend more than $10 million on ads in Iowa and New Hampshire, including broadcast, cable, radio, mail and digital. According to AdImpact, the campaign spent $2.2 million on TV, digital and radio ads since that announcement.

“Presidential TV ad spending is idiotic, low-ROI & a trick that political consultants use to bamboozle candidates who suffer from low IQ,” Mr. Ramaswamy said on X Tuesday. “We’re doing it differently. Spending $$ in a way that follows data … apparently a crazy idea in US politics.”

“Big surprise coming on Jan. 15,” he said, referring to the day of the Iowa caucus.

According to the political statistics website FiveThirtyEight’s average of recent national polls, Mr. Ramaswamy comes fourth behind Mr. Trump, Florida Gov. Ron DeSantis and former South Carolina Gov. Nikki Haley.
