US Vice President Kamala Harris told her supporters in Nevada on Saturday that she supports repealing the tax on tips, taking a similar position to her rival Donald Trump as she seeks to win over service workers, a key voting bloc in the state.

Harris and her Democratic running mate, Minnesota Governor Tim Walz, ended a multi-day tour of swing states on Saturday with a stop in Nevada, a western U.S. state that could play a decisive role in the November 5 presidential election.

“I promise everyone here that as president, we will continue to fight for the rights of working families, including raising the minimum wage and eliminating the tax on tips for service and hospitality workers,” Harris said.

Harris said she would fight for lower consumer prices and vowed to “deal with big companies that engage in illegal price gouging” – business owners who unfairly drive up rents for working families – and big pharmaceutical companies that want to lower drug prices.

At a rally in Las Vegas in June, Trump said he would work to abolish taxes on tips.

Harris, who was officially named the Democratic Party’s presidential nominee this week, has been campaigning with Walz in Wisconsin, Michigan and Arizona, all states that traditionally swing between Republican and Democratic support in presidential elections. To become president, a candidate must win not the national majority vote but 270 electoral votes. Each state has a number of electoral votes based on its population, making swing states especially important. She will travel to San Francisco in her home state of California on Sunday, where she is scheduled to attend a fundraiser with former House Speaker Nancy Pelosi. Nearly 700 people are expected at the event, which aims to raise more than $12 million, a campaign official said.

Harris and Walz, whose nomination she announced on Tuesday in Pennsylvania – another swing state – are looking to maintain and build on the momentum Harris has generated since President Joe Biden stepped down as party leader last month.

In separate polls conducted by the New York Times and Siena College in Wisconsin, Michigan and Pennsylvania, another swing state, Harris was four percentage points ahead of Republican former President Trump. That’s a stark difference from polls conducted before Biden dropped out of the presidential race.

The Trump campaign released a memo from its pollster Tony Fabrizio rejecting the results. “Once again, we see a series of public polls released with the clear intent and goal of dampening support for President Trump,” Fabrizio said.

Nationally, Harris was ahead of Trump by five percentage points, 42% to 37%, in an Ipsos poll released Thursday, even larger than in a Reuters/Ipsos poll released on July 22-23, which showed her lead at 37% to 34%.

Harris has raised hundreds of millions of dollars and held rallies with thousands of supporters since becoming the Democratic nominee, regularly outshining Biden’s smaller events and drawing the ire of Trump, for whom crowd size has always been a key measure of political strength.

The Harris campaign said there were more than 12,000 people in the Las Vegas arena on Saturday and police turned away about 4,000 more because people in line became sick as temperatures rose in the Nevada heat, where temperatures reached as high as 40 degrees Celsius on Saturday.

Harris has spent the week highlighting differences with Trump. On Saturday, before leaving Arizona, she said she disagreed completely with the former president on the Federal Reserve.

She said she would not interfere in the affairs of the independent Fed if she were elected president, a stark contrast to Trump, who said on Thursday that presidents should have a say in the central bank’s decisions.
