The speech will also be an opportunity for Mr. Biden to focus on falling gas prices, a booming job market and legislative victories on climate change, drug prices, infrastructure improvements and veterans’ health care.

But Mr. Biden is leaning into more political attacks, aides and allies said, in part because of what he sees as a growing embrace of violent political speech by Republicans and a threat to the democratic process of governing. The aides said he was dismayed by the number of Trump-backed election deniers who have won Republican primaries for governor or secretary of state across the country.

Mr. Biden, whose own approval ratings have begun to improve slightly since lows earlier this summer, is hoping that his party can maintain control of Congress and deliver a forceful rebuke to Mr. Trump and his followers.

It is a moment, one adviser said, to make sure people understand what is at stake.

“Given everything that is happening right now, I have to imagine that this is weighing on him very heavily,” said Symone D. Sanders, who served as the chief spokeswoman for Vice President Kamala Harris and now hosts a new MSNBC show. “He feels as though he needs to ring the alarm, sound the alarm as he did throughout all of 2019, throughout all of 2020 in the lead-up to the election.”

Republicans have noticed the new tone. Ronna McDaniel, the chairwoman of the Republican National Committee, said on Wednesday that the president was “the divider in chief and epitomizes the current state of the Democrat Party: one of divisiveness, disgust and hostility toward half the country.”

Mr. Trump is scheduled to hold a rally in Wilkes-Barre, Pa., on Saturday, just two days after Mr. Biden’s planned speech in Philadelphia and four days after the president made his own visit to Wilkes-Barre. Pennsylvania, a swing state, is home to key races for the House and Senate as well as a closely watched governor’s race.
