Biden faces mounting pressure to drop out as Harris takes the campaign spotlight.

• In North Carolina, Kamala Harris campaigned on the train, garnering intense media attention as the presumptive Democratic Party nominee if Biden decides not to run for re-election.
• On Thursday, the vice president made comments while under immense pressure from leading Democrats to withdraw from the presidential race.
• Last week, a source informed NBC News that the Biden campaign has been secretly evaluating the possibility of a Harris-led ticket in opposition to Trump.

On Thursday, Vice President Kamala Harris highlighted the revival of domestic manufacturing under President Joe Biden during a campaign stop in North Carolina, where the media's focus on her reflected her potential to become the Democratic Party's presidential nominee if Biden decides not to run again.

"Under President Donald Trump, America lost tens of thousands of manufacturing jobs and more than 1,000 factories closed. However, under President Joe Biden and Vice President Kamala Harris, nearly 800,000 new manufacturing jobs have been created, resulting in a manufacturing boom."

Amidst pressure from top Democrats, the vice president made remarks about the presidential race.

Both Chuck Schumer and Nancy Pelosi have conveyed to Biden that his reelection could jeopardize the party's prospects in both houses of Congress, as per media reports.

According to two sources close to former President Barack Obama, he has reservations about Joe Biden's ability to maintain his position as the Democratic Party's top candidate, but continues to view his primary responsibility as offering guidance and support to his longtime vice president.

As Democratic megadonors push for Biden to step down, events featuring Harris are becoming increasingly popular and are selling out.

Despite testing positive for Covid-19 and self-isolating in Delaware, Biden has consistently refused to withdraw from the presidential race.

Last week, a source informed NBC News that his campaign has been privately evaluating the possibility of a Harris-led ticket and conducted polls to assess her chances of winning against former President Trump in a head-to-head race.

A recent CBS/YouGov poll of likely voters indicates that the Republican presidential nominee has a 5-point advantage over Biden, 52% to 47%, while in a hypothetical match-up, Trump leads Harris by 3 points, 51% to 48%. Both results are within the margin of error, and the poll was conducted after the attempted assassination of Trump on Saturday.

Harris addressed Vance's speech at the Republican National Convention in her remarks Thursday, which were aired live by MSNBC, CNN, and Fox News.

"Harris stated that Trump did not discuss Project 2025, a 900-page blueprint for a second term, because the plans are extreme and divisive, as they were developed by The Heritage Foundation, a conservative think tank."

"If you claim to stand for unity, you need to do more than just use the word," Harris said. "You cannot claim you stand for unity if you are pushing an agenda that deprives whole groups of Americans of basic freedoms, opportunity and dignity."

On Wednesday, Harris, who campaigned in Michigan, highlighted the administration's accomplishments, including the insulin price cap, the expansion of the child tax credit, and student debt relief.

If Donald Trump wins in November, he will persist in betraying working families, attacking reproductive rights, and eroding our democracy, according to Harris.

This month marks the second visit of Harris to North Carolina, a battleground state where Democrats are hoping to win after a close loss to Trump in 2020.

On July 11, Harris spoke at a campaign event in Greensboro, accompanied by Gov. Roy Cooper, the Democratic governor who is not seeking reelection. Cooper, who was the attorney general of North Carolina at the same time Harris was the attorney general of California, also addressed the crowd at the rally.
