According to the president of one of the largest super political action committees (PACs) supporting Kamala Harris, her supporters should not be too confident that she is ahead of Donald Trump in recent polls.

Chauncey McLean of Future Forward USA said at a panel at the University of Chicago’s Institute of Politics that the internal poll numbers are “much less rosy” than what the public sees.

“We have it absolutely under control, across the board,” McLean said.

His comments came as the vice president was set to be crowned the party’s nominee at the Democratic National Convention in Chicago this week.

According to polls consolidated by FiveThirtyEight, Harris is nearly three points ahead of Trump, according to RealClearPolitics, Harris is 1.5 points ahead, and according to the Cook Political Report, Harris is less than a point ahead.

Current surveys from The New York Times/Siena College, Emerson College and CBS/YouGov have confirmed that Harris is leading Trump by a slim margin – even in some key swing states. These numbers are quite a change from just a month ago, when Trump was several points ahead of Joe Biden.

Biden’s exit from the 2024 presidential race was partly due to his poll numbers, which had suffered significantly following his poor performance in the first election debate.

Since he left his party and endorsed Harris, Democrats have seen an upward trend in poll numbers, boosting their confidence of winning the election.

But McLean says Future Forward’s poll results suggest the race is still extremely close.

“We’ve spoken to 375,000 Americans since the vice president was nominated,” McLean said. “What you see in the public polls – you know, a big public poll is (only) 1,000 polls.”

But Harris’ entry into the 2024 race has opened up several paths to victory that weren’t necessarily available to Biden, thanks to newfound support from young people of color, McLean said.

To win, however, Harris would still have to win one of the three crucial swing states – Georgia, North Carolina or Pennsylvania – Reuters reported.

McLean said Future Forward has at least $250 million left to spend through a digital advertising campaign and a TV ad campaign that will run from Labor Day through Election Day.

According to OpenSecrets, the Super PAC has so far raised $134 million to support the Harris campaign.
