WATCH: Trump appears at campaign rally in Tucson, first since debate with Harris

Former President Donald Trump appeared at a campaign rally in Tucson, Arizona, as he looks to stabilize his campaign, which continues to struggle to recalibrate nearly two months after Harris replaced President Joe Biden at the top of the Democratic ticket.

Trump said Thursday that as president he’d seek to end taxes on overtime wages. It’s his latest appeal to the working-class voters he’s counting on to return him to the White House. Trump has also pledged to end taxes on tips and Social Security wages.

The proposals would take a significant bite out of federal revenue, ballooning the deficit unless accompanied by significant spending cuts.

“It’s time for the working man and woman to finally catch a break,” Trump said. Harris has announced her own proposal to stop taxing tips.

Arizona is a state where the presidential race could be shaped, at least in part, by down-ballot races. Kari Lake, a prominent Republican election denier who lost her campaign for governor in 2020, is running for the U.S. Senate seat that’s being vacated by Kyrsten Sinema.

Lake exemplifies the rightward shift of the state party in the Trump era. She’s opposed by Democratic Rep. Ruben Gallego, who was leading in several recent polls, although the race was close in another.

Republicans have won Arizona in nearly every presidential election since World War II, but Biden eked out a narrow victory in 2020.

The rise of Arizona Democrats has been driven by the arrival of transplants from blue states and a political realignment that has seen suburban voters — particularly college-educated women — shift away from Republicans.

Minnesota Gov. Tim Walz, Harris’ running mate, held a rally in the state on Tuesday ahead of the debate, and the Democratic ticket campaigned together there last month.

Republicans still outnumber Democrats in Arizona, but one-third of voters are independent. Ohio Sen. JD Vance, Trump’s running mate, appeared last week in a heavily Republican area of metro Phoenix with Charlie Kirk, the founder of an influential conservative youth group.

Trump was last in Arizona two weeks ago for a news conference along the U.S.-Mexico border, where he drove one of his most effective attacks on Harris over the number of people crossing the border to seek asylum, followed by a rally at a former hockey arena in the Phoenix area.

Both candidates will stay on the road in the coming days. Trump will head to Los Angeles on Thursday night for a fundraiser, then plans to speak to the media on Friday morning before raising more money in the Bay Area and continuing on to Las Vegas for another rally.

Meanwhile, Harris is going to Johnstown and Wilkes-Barre in Pennsylvania on Friday.
