In the run-up to Tuesday night’s debate, the battle between Trump and Harris is tight in key states where the battle for victory will take place, the latest CBS News/YouGov poll performed last week.

The poll showed Harris with 50% in Michigan to Trump’s 49%. The two were tied in Pennsylvania at 50%, and Harris had a one-point lead, 51% to 49%, in Wisconsin.

According to the same poll, Harris generates slightly more enthusiasm among Democratic voters in those key states than Trump does among Republican voters.

The presidential debate begins at 9 p.m. Eastern Time and lasts 90 minutes, with two commercial breaks.

There will be no opening statements — questioning by moderators David Muir and Linsey Davis of ABC will begin immediately. Both candidates will have two minutes for closing statements at the end of the debate.

The debate will be hosted by ABC News, which will allow other networks to simulcast it. CBS News’ primetime coverage begins at 8 p.m. ET — check your local listings.

The former president has been discussing policy positions with advisers in the lead-up to the debate, sources familiar with the former president’s preparations told CBS News. However, his preparations have been described as somewhat informal, including talking to voters and interacting with the media.

In a phone call with reporters on Monday, Trump adviser Jason Miller said preparing for a debate with Trump is like “preparing for Floyd Mayweather or Muhammad Ali.”

“You don’t know what angle they’re going to come at you from. You don’t know what style of contrast they’re going to deliver. There’s a great mix of humor and charm, and also some very hard facts about why we’re doing this, because Americans are suffering,” Miller said.

“In this debate, President Trump will hold Kamala Harris up on her record, her record on the border, her record on global instability, and her record as a swing vote for high prices,” Miller added. “And if President Trump holds Kamala Harris up on her record, which we know very well he will do, it will be a success, because the American people will see what a dangerous radical liberal she is.”

Trump told “Good Morning New Hampshire” last week that he’s been “preparing for this debate his whole life.”

“So, you know, I do. I have meetings about it,” Trump added. “We talk about it, but there’s not much you can do.”

The vice president was in Pittsburgh over the weekend preparing for the debate before arriving in Philadelphia on Monday. She practiced with elaborate mock debates on a stage with lights to recreate the debate environment, while focusing on policy and attempting to create a contrast with the former president. In preparation for the debate, Philippe Reines, a former aide to Hillary Clinton, played Trump, with a source saying he even dressed as the former president.

After Harris’ campaign’s failed attempt to turn on both candidates’ microphones during the debate, the vice president and her team also used the time in Pittsburgh to go back to the drawing board on their debate strategy, a senior campaign official said. Harris had planned to pepper Trump with questions, but her campaign had to find a new approach because of the limitations of the microphones.

Harris’ surrogates have appeared to downplay expectations for the debate, such as Transportation Secretary Pete Buttigieg, who told CNN that “it’s going to take almost superhuman focus and discipline to deal with Donald Trump in a debate.” Buttigieg was involved in planning for Harris’ 2020 debate against former Vice President Mike Pence.

“It’s not a run-of-the-mill proposal,” Buttigieg said. “It’s not because Donald Trump is a master at laying out policy ideas and how they’re going to make people better off. It’s because he’s a master at taking whatever form or format is on television and turning it into a show that’s all about him.”
