Former President Donald Trump on Monday rallied caucus-goers in Iowa’s rural Dallas County, where he received the endorsement of the state’s attorney general and predicted a landslide victory. Trump has ramped up his campaigning in the states three months before voting begins in the GOP contest’s kickoff state. Trump's advisers want to lock in support not only to avoid a repeat of his second-place finish in 2016 but to win a blowout victory that denies his second-place finisher major momentum.
