Prominent pollster Nate Silver remarked to Sirius XM’s Megyn Kelly on Tuesday that Democrats might be “getting carried away” with Vice President Kamala Harris, who is widely expected to be the party’s presidential nominee in 2024.

Silver indicated to Kelly that the contest between Harris and her Republican challenger is currently as tight as a “coin flip.”

“The polls can be off. They were off in 2016 and 2020. In 2020, Biden had a big enough lead in the polls that he held on, but they were off by four or five points in states like Wisconsin,” Silver said.

President Joe Biden won Wisconsin in the 2020 election by a narrow margin of 20,682 votes, or 0.6% of the total vote. Kelly noted that many Republicans are “starting to get very worried” about Trump’s prospects, as the GOP nominee “looked so much better” four weeks ago compared to his current standing.

On July 13, during a rally in Butler, Pennsylvania, Trump narrowly escaped harm when a bullet grazed his ear. The former president, who stood up, raised his fist and shouted “Fight!” after the incident, made his first public appearance following the assassination attempt at the Republican National Convention (RNC) on July 15.

“Democrats may be getting a little carried away here,” Silver told Kelly. “Kamala Harris is going to have her convention next week, and typically, that produces a further boost in the polling. So, I think August will remain rough month for the GOP. In September, she will face a different type of pressure. The pressure of being a perceived frontrunner potentially can be more difficult. Being an underdog is a powerful kind of constituent or powerful meme in American politics. It’s a sympathetic situation and in some ways, it’s a great story.”

Harris holds a narrow lead over Trump in Wisconsin by 0.8% and in Michigan by 2.4%, according to RealClearPolitics polling averages. Meanwhile, Trump is ahead in Pennsylvania by 0.8%, Georgia by 0.6%, Arizona by 1.5%, and Nevada by 3.7%.

“When you’ve been watching the media, it’s been such a whiplash, right, of them eventually deciding Biden had to go. ‘Okay, we’re gonna do our shoe-leather reporting, let’s get to the bottom of this. We’re suddenly interested in all of his fails and stumbles.’ And then as soon as she got anointed, it was like, ‘Not interested anymore!’” Kelly added.
