Joe Biden on Saturday completed his Texas campaign swing in Dallas, telling some of the state's most prolific donors that he can beat Donald Trump and restore the nation's reputation at home and abroad.

"If we allow him four more years, I really, honestly believe it will change the nature of who we are as a country," he said.

The former vice president said that Trump has stoked hate and division in America, and that the nation should unite to fight against such intolerance.

"Hate only hides, it doesn't go away," Biden said at the Preston Hollow home of Drs. Lisa and David Genecov. "If you give it any oxygen, hate comes out from under the rocks."

Biden invoked former President Ronald Reagan, a political opponent, when he said America needed to regain its standing as the "shining city upon a hill."

"We can overcome four years of Donald Trump," he said.

But a spokeswoman for Trump's victory campaign said Biden would be bad for Texas.

"Joe Biden's embrace of radical policies such as eliminating fossil fuels and providing free health care to illegal immigrants won't resonate well in the Lone Star State," said Samantha Cotten. "As Biden lines his campaign coffers with cash from out-of- touch elites, Texans know that President Trump has delivered on his promises and will work to Keep America Great."

After participating in the third Democratic Party presidential debate Thursday night, Biden attended fundraisers in Beaumont, Houston and Dallas.

He's the national front-runner in a crowded Democratic field that includes former Rep. Beto O'Rourke of Texas and former Housing Secretary and former San Antonio Mayor Julian Castro.

Recent polls show Biden leading the field in Texas, with O'Rourke trailing the former vice president and Massachusetts Sen. Elizabeth Warren.

Texas could play a critical role in the 2020 Democratic primary. The contest is on March 3, with the Lone Star State dangling 262 delegates.

O'Rourke has a public rally in Plano on Sunday, along with a fundraiser in Oak Lawn.

Saturday marked Biden's second trip to Dallas since he launched his presidential campaign.

In May, Biden was in town for a fundraiser at the Highland Park home of Dallas lawyer Russell Budd and a town hall meeting with students from the Mayor's Intern Fellows Program at SPARK, a nonprofit that boosts children.

The hosts of Saturday's event were Dallas lawyer Lisa Blue Baron, former ambassador to the Dominican Republic James W. Brewster and Bob Satawake, Dallas lawyer Russell Budd and Dori Budd, the Genecovs, Dallas lawyer Peter Kraus and Lisa Kraus and Dallas lawyer Marc Stanley and Wendy Stanley.

The co-chairs for the afternoon reception were asked to raise $25,000, and individual tickets started at $1,000. If you kicked in $2,800, you got a photo with Biden. The reception, as usual, was closed to the public.

David Genecov introduced Biden as a great candidate against Trump.

"Joe Biden is by far the best chance to move the country forward," he said.

Marc Stanley said the crowd of about 130 was moved by Biden's remarks.

"It was a great event," he said. "He really inspired everybody in the room to work hard to defeat Donald Trump."

Biden acknowledged state Rep. Victoria Neave of Dallas, who endorsed him this week. He also said Dallas had a great mayor, referring to Mike Rawlings, who was replaced by Mayor Eric Johnson in June.

He then told the gathering that local Democrats would have a strong 2020.

"I think you're going to turn Texas blue," he said.
