Vivek Ramaswamy will make a swing through Michigan on Tuesday as he seeks to capture voters in a swing state seen as a battleground for blue-collar workers.

Both President Biden and former President Donald J. Trump visited the state just days apart last week — Mr. Biden joined the picket line with striking members of the United Automobile Workers, while Mr. Trump spoke at a nonunion factory.

Mr. Ramaswamy’s return to the Great Lakes State on Tuesday will close with a rally opposing plans for an electric vehicle battery factory that has become a flashpoint in the state, heightening U.S.-China-related tensions.

Gotion, a Chinese subsidiary, has sought to a build $2.4 billion electric vehicle battery factory spanning 270 acres in Green Charter Township, a rural Michigan town. Despite the factory’s potential to bolster the local economy, “No Gotion” signs have popped up as residents fear an infiltration by the Chinese Communist Party — though the company insists it has no ideological ties to China or affiliations with political parties.

Several Republican presidential candidates, including Mr. Ramaswamy, an entrepreneur, have argued against allowing Chinese companies to purchase American land. Criticism of electric vehicle production has also become standard in the race.

Wednesday will be Mr. Ramaswamy’s second visit to the state in as many weeks. He attended the Mackinac Republican Leadership Conference in September.

His first stop Wednesday will be a breakfast rally in Saginaw, followed by a town hall in Flint. The rally “opposing China’s Gotion electric battery plant” will be in Big Rapids.

Other G.O.P. candidates have focused more of their energy on Iowa, New Hampshire and South Carolina, states with primaries that will be held before Michigan’s.

Gov. Ron DeSantis of Florida will campaign in South Carolina on Wednesday for the first time in months, after his last scheduled trip there in August was derailed by Hurricane Idalia.

And Senator Tim Scott of South Carolina will be in Van Cleve, Iowa, hosting a town hall as he tries to ramp up support while his poll numbers dwindle.
