Republican Donald Trump on Monday evening appealed to religious voters in the southern swing state of Georgia as his campaign distanced itself from racist remarks by supporters that could alienate key voter groups.

Millions of Americans have already cast their vote before the November 5 election, which national polls including the latest one from Reuters/Ipsos, and surveys in swing states, show is a close race between Trump and his Democratic rival Kamala Harris.

In Georgia, where in-person early voting ahead of Election Day is expected to total up to 70 percent of ballots, Trump courted religious voters during a National Faith Advisory Board event.

"I think this is a country that needs religion," Trump said. "They're trying to stymie you, this new administration, this new radical left group of people."

But he faces pressure over his rally in New York on Sunday, where a comedian called Puerto Rico a "floating island of garbage," prompting a backlash from Latino celebrities and criticism from both Republican and Democratic politicians. The Trump campaign has said the joke did not reflect their views.

Some 46 million Americans have voted already, according to the Election Lab at the University of Florida, including some 2.8 million people in Georgia and 1.9 million people in Michigan, where Harris arrived on Monday.

Harris visited Corning Inc's Hemlock Semiconductor facility to talk to workers and tour the assembly line and talk about the importance of investing in manufacturing jobs.

The company recently received a preliminary investment of up to $325 million via the Chips and Science Act, which a Harris campaign official noted Trump had criticized and Harris helped pass.

"When we can find a way to have meaningful partnerships with the private sector, with industries, but to do the kind of work that is happening here, everybody wins," she said.

Trump has argued his stewardship of the economy was stronger than that of President Joe Biden and Harris, despite major job losses at the end of his term at the onset of the coronavirus pandemic.

Though the US job market has been strong under the Biden-Harris administration and stock markets have hit record highs, persistently elevated prices have hammered consumers on everything from groceries to rent.

Harris has issued policy proposals to bring down prices and help alleviate the country's housing crunch, while also contrasting her leadership approach with Trump, who she said would be focused on getting back at his enemies.

On Monday evening, Harris appeared at a rally in Ann Arbor, Michigan with her running mate, Minnesota Governor Tim Walz, that featured a performance by singer-songwriter Maggie Rogers.
