Former President will be in southeast Iowa on Sunday in the aimed at locking in supporters with large organizing events.

As he has with his other recent travels to the leadoff caucus state, Trump will campaign but has embraced him.

Trump was planning to headline an afternoon event in Ottumwa, where his campaign was expecting more than 1,000 potential supporters. The small city is a hub in eastern Iowa and the seat of Wapello County, one of 31 counties Trump carried in 2016 that Democrat Barack Obama had won four years earlier.

Trump, the first Republican to capture the county since the Eisenhower administration, campaigned the week before in northeast Iowa. There, he drew about 1,400 to rural Jackson County along the Mississippi River and almost 2,000 to Dubuque County to the north. Like Wapello, Dubuque County had been a Democratic stronghold for decades before 2016.

Though aides said they were not specifically targeting counties that Trump flipped in 2016, they noted that he has had success in the eastern part of Iowa where manufacturing has declined sharply in the past two decades. His administration鈥檚 renegotiation of the U.S. trade pact with Canada and Mexico remains popular.

Rick Anderson and his wife Nancy, who were filing into Ottumwa鈥檚 Bridge View Center, are the kind of voters whom Trump鈥檚 campaign would like to persuade to caucus for the candidate on Jan. 15. They used to vote Democratic but switched in 2016 to support Trump. They have not attended Iowa鈥檚 Republican precinct caucuses in the past.

Rick Anderson, a retired union millwright who co-owns a small business with his wife, is among the many longtime union members who kept Wapello County and others in Iowa鈥檚 once-robust, eastern manufacturing corridor reliably Democratic-performing until Trump.

鈥淲e like what he says. He says 鈥楧rill, baby, drill,鈥� and that鈥檚 got my heart. Because that鈥檚 what鈥檚 wrong with the country is energy. Solve that problem and you solve so many other problems,鈥� Anderson said. 鈥淒emocrats have lost touch with people like us.鈥�

As Trump maintains a strong lead in Iowa, his Republican rivals are , hoping a strong showing can help them consolidate the non-Trump support.

Trump volunteers at the site held clipboards stacked with pledge cards and asked attendees whether they would commit to support Trump at the caucuses.

Trump arrives in Iowa after a two-day trip to California, where he picked up 6 million of his 74 million votes in 2020 while losing the state by 30 percentage points to Democrat Joe Biden.

In a fiery speech that delighted Republicans dejected after decades of Democratic control, his long-standing tough-on-crime message with calls for violent retribution for against criminals. People caught robbing stores should be shot, Trump said to applause. He raised money during his trip to Orange County, once a bastion of conservatism in Southern California that has become increasingly competitive.

While Trump鈥檚 would-be Republican challengers , Trump was in another key blue-collar county in the general election battleground of Michigan. Trump spoke during Wednesday night鈥檚 debate in Macomb County, Michigan, north of Detroit at a nonunion manufacturing plant, where he blasted Biden鈥檚 push for electric cars amid an autoworkers鈥� strike. Trump carried Macomb County twice, after Obama did in 2008 and 2012.

Trump is ramping up his travel in Iowa, which kicks off the Republican nomination calendar with the Jan. 15 caucuses. He has scheduled several visits to the state this month.
