The former president has set sky-high expectations for his own performance in the first contest of the race for the Republican presidential nomination. He spent the day before the caucuses trying to ensure he meets them. His main GOP rivals all spent Sunday in Iowa as well, making last-minute appeals to Iowans open to hearing them.

At a rally in Indianola, Trump said his supporters could fight back against his political enemies, claiming that the four indictments he faces were driven by politics and renewing his false claims about the 2020 election he lost to Democrat Joe Biden.

Many in the crowd wore white and gold caps identifying them as Trump caucus captains who will help round up support for him Monday night.
