Members of Donald Trump’s team are quietly preparing to go on offense against Robert F. Kennedy Jr. as internal campaign polling suggests his expected third party bid could draw more votes from Trump than President Joe Biden in a general election.

Semafor has not independently reviewed the polling. One person close to Trump’s campaign said it showed that Kennedy took more votes from Trump than left-wing independent Cornel West drew from Biden when both were tested.

“It’s single digits, but it’s enough where it counts to make a difference,” the person said. A second person familiar with the polling confirmed their description.

With Trump allies “anxious,” as one supporter put it, his campaign and outside allies are also preparing to release an onslaught of opposition research.

“We’re gonna be dropping napalm after napalm on his head reminding the public of his very liberal views, dating back to 2012,” another Trumpworld person told Semafor. “We have a lot of stuff on him.”

While it’s not clear if it’s related, the Daily Caller published a story today dredging up Kennedy’s comments from two decades ago that “factory meat integrators are more threatening to democracy than Osama bin Laden.” The same story also mentioned his description of the NRA as a “terror group” after the 2018 Parkland shooting.

RFK Jr. has himself suggested he’d be likely to rely on Republican support, saying in a recent podcast interview that he “take[s] more votes from President Trump than” from Biden. A pro-RFK Jr. super PAC produced polling suggesting as much, albeit at the margins and without other third party options included.

Democrats seem largely unconcerned about Kennedy’s campaign, though there is some divide among independent pollsters over how he might affect the race. One poll by Republican firm Echelon Insights found he drew slightly more voters from Biden, whose support they argued was more tenuous than Trump’s overall.
