New polls show the Democratic and Republican candidates are in a dead heat with less than a month to go before the vote.

A series of polls show Kamala Harris losing ground to Donald Trump less than a month before the election for President of the United States.

Harris' lead over Trump has narrowed or disappeared as the race for the White House nears the home stretch, according to three polls released Sunday.

In the latest NBC News poll, the Democratic and Republican candidates are tied at 48 percent nationally ahead of the Nov. 5 vote, a reversal from a five-point lead for Harris in the same poll last month.

In the latest ABC News/Ipsos poll, Harris leads among likely voters 50 percent to 48 percent. In the same poll last month, the Democrat was ahead 52 percent to 46 percent.

The latest CBS News/YouGov poll shows Harris up 51 percent to 48 percent among likely voters, compared to a four-point lead last month.

According to the latest figures, Harris is ahead by 1.4 percentage points in all of Real Clear Polling's major polls, compared to 2.2 percent on Saturday.

The falling poll numbers come as Democrats worry that Harris is failing to shore up support among Hispanics and African Americans, two of the party's key voter groups.

While Harris leads among women of all races, she has struggled to generate enthusiasm among men, including African Americans and Hispanics, who have increasingly drawn to Trump in recent years.

In New York Times/Siena College polls released Saturday and Sunday, Harris received the support of 78 percent of Black voters and 56 percent of Hispanic voters — significantly lower shares than the Democratic candidates in the 2020 and 2016 elections.

On Thursday, former President Barack Obama admonished black men for not showing as much enthusiasm for Harris' candidacy as he received during his 2008 and 2012 campaigns.

“They come up with all kinds of reasons and excuses, and I have a problem with that,” Obama said at a campaign rally in Pittsburgh, Pennsylvania, one of seven key states where the election is expected to be decided.

“Because part of it makes me think – and I'm speaking directly to men – part of it makes me think that you just don't feel the idea of ​​having a woman as president, and you come up with other alternatives and other reasons for it.”

Harris and Trump continued to focus their campaigns on battleground states on Sunday, holding events in North Carolina and Arizona, respectively.

At a campaign rally in Greenville, North Carolina, Harris took aim at Trump for spreading misinformation about the government's response to recent hurricanes.

“The problem with this, beyond the obvious, is that it makes it harder to get life-saving information to people by making them believe they can't trust it,” Harris said.

“And that's the pain of it all, which is the idea that those in need are somehow convinced that the forces are working against them in such a way that they wouldn't seek help.”

Trump, meanwhile, used a rally in Prescott Valley, Arizona, to call for the hiring of 10,000 additional Border Patrol agents.

“After I win, I will immediately ask Congress to approve a 10 percent raise for all agents – there hasn't been one in a long time – and a $10,000 bonus each for retention and signing,” Trump said . “We’ll keep them.”
