Sixty-four percent of likely voters said Robert F. Kennedy Jr.’s endorsement of former president Donald Trump doesn’t change their view of the Republican presidential nominee, a new poll from Quinnipiac University found.

Kennedy suspended his own independent bid for president last week and backed the former president. Nineteen percent of likely voters said the endorsement made them think “more favorably” of Trump. Meanwhile, another 15 percent said Kennedy’s support makes them think “less favorably” of Trump.

Before Kennedy suspended his campaign last week, his running mate Nicole Shanahan said the campaign didn’t want to serve as a “spoiler candidate” by pulling votes from Trump. But the Kennedy campaign appeared to be running out of steam even before Shanahan’s comments, raising just $5.6 million last month while spending $7 million, according to the latest FEC filings. The campaign had also not held a public event in over a month.

“Independents, so critical to the outcome of the race, aren’t exactly swayed by [Kennedy] to change their views about Trump,” Quinnipiac University polling analyst Tim Malloy said in a statement.

Forty-two percent of respondents said they had an unfavorable view of Kennedy, compared to 32 percent who had a favorable view of the Democrat-turned-independent. Twenty-four percent said they did not know enough about him to have an opinion.

The Quinnipiac poll found Harris and Trump neck-and-neck, garnering 49 percent support and 48 percent support, respectively.

The poll was conducted between August 23 and 27 among 1,611 likely voters and has a margin of error of 2.4 percentage points.

Before Kennedy dropped out of the race, five-way national polling that included Harris, Trump, Kennedy and third-party candidates Jill Stein and Cornel West, found Kennedy pulling an average 4.5 percent support, according to RealClearPolitics. Harris, meanwhile, led Trump 46.4 percent to 44.9 percent. In a head-to-head matchup, Harris leads Trump an average of 48 percent to 46.2 percent.

After dropping out, Kennedy said he would try to pull his name from the ballot in key battleground states, in an effort to boost Trump’s odds. However, Michigan and Wisconsin have refused to remove his name from their ballots.
