A number of Republican Senate candidates made their pitch to voters by criticizing the policies of the Biden administration, arguing they have made Americans less safe. The Senate Democrats they’re challenging have rubber stamped Mr. Biden’s agenda, they said. 

Former Rep. Mike Rogers, who is looking to replace Democratic Sen. Debbie Stabenow in the Senate, accused the Biden administration of trying to force Americans to buy electric vehicles as they face the high costs of groceries and rent. 

Bernie Moreno, who’s challenging Democratic Sen. Sherrod Brown in Ohio, walked out to chants of “Bernie! Bernie! Bernie!” He recalled his family immigrating to the U.S. from Colombia “legally.” He claimed Democrats have “put the welfare of illegals ahead of our own citizens.” 

“They’ve destroyed our border. They’ve destroyed our economy. They’ve destroyed our standing in the world, and they’ll destroy America if we don’t stop them,” he said. 

Hung Cao, who was born in Vietnam and is challenging Democratic Sen. Tim Kaine of Virginia, also touched on immigration. 

“As an immigrant to this great country, let me be very clear to everyone who comes here. Don’t ask for the ‘American Dream’ if you’re not willing to obey the American laws and embrace American culture,” Cao said. 

Tim Sheehy, a former Navy SEAL running against Democratic Sen. Jon Tester of Montana, said the “world is on fire” under Mr. Biden’s leadership. He argued there has been “zero accountability” for the disastrous withdrawal from Afghanistan and said he is running “to bring back accountability to our government.” 

Nevada Senate candidate Sam Brown, an Army veteran who nearly died in an explosion in Afghanistan, asked attendees to look at his scarred face. 

“This is the high cost of war,” Brown said. “If Joe Biden stays in office, more service members will pay this price.” 

Dave McCormick, the candidate taking on Democratic Sen. Bob Casey in Pennsylvania, said “the choice this November is clear.” 

After criticizing Mr. Biden’s border policies, Eric Hovde, the GOP candidate Wisconsin Sen. Tammy Baldwin, shifted, saying the country “has become too divided.” 

“We need to heal this country from the division that the left has brought. And the media, you have to stop dividing us,” he said.
