President Joe Biden was quick to endorse Vice President Kamala Harris this past weekend after announcing that he will not be his party's nominee.

Yet while Harris has the support of many high-profile Democrats, polling data suggests she may face a nightmare race against former President Donald Trump. 

New survey finds that Trump has a double-digit lead over Harris

As Breitbart noted, a Harris X/Forbes survey carried out between July 19 and July 21 showed Harris as being supported by just 42% of likely voters compared with 52% who favored Trump.

When undecided voters were prompted to make a selection, the vice president's support level grew to 46% while Trump's climbed to 54%.

Harris' numbers among African American and Latino voters are especially bad

Unsurprisingly, Democratic and Republican likely voters were both found to overwhelmingly favor their respective party's candidate.

However, Trump showed more strength among independent voters, winning 48% of them. Meanwhile, just 33% of independents expressed a willingness to back Harris.

A breakdown of voters by race had Harris losing whites while winning with African Americans and being tied among Hispanic voters.

Harris' 65% share of the black vote is historically low for a Democrat, as polling by Pew Research found that 92% of African Americans supported President Biden four years ago. She is particularly weak among black men, with a mere 54% backing her.

Her popularity level with Hispanics also appears to be far lower than Biden's was, as Pew Research found that the president received 59% of the Latino vote in 2020.

Recent Quinnipiac University poll also shows Harris losing to Trump

The Harris X/Forbes survey wasn't the only potential source of concern for Democrats, as Fox News reported that a Quinnipiac University poll put out on Monday carried ominous signs as well.

It showed Trump as being supported by 49% of voters compared with 47% who plan to cast a ballot for the vice president. When other candidates such as Robert F. Kennedy Jr., Dr. Cornel West, and Jill Stein were included in the poll, Trump's advantage grew from two points to four.

"The dramatic reset at the top of the Democratic ticket does little to move the race as Vice President Harris enters the fray with numbers similar to President Biden," Quinnipiac University polling analyst Tim Malloy was quoted as saying.
