"Trump's Dominance Grows as Iowa Caucuses Loom"

With 50 days until the Iowa caucuses, former President Trump holds a commanding lead in the Republican presidential nomination polls, while Florida Governor Ron DeSantis and former ambassador Nikki Haley battle for second place. DeSantis aims to follow the footsteps of previous Iowa caucus winners by visiting all 99 counties in the state, while Haley has gained momentum in recent months and aims to make a fight of it in Iowa. Other candidates, including Vivek Ramaswamy, Doug Burgum, Chris Christie, and Asa Hutchinson, are also campaigning in Iowa, but Trump's dominance in the state is expected to have a significant impact on the race.
