The state’s most devoted Republican caucus-goers were undeterred, defying snowy driveways, icy roads and speculation of lower turnout to show up and throw their support behind the former president. In total, Edison Research estimated turnout at 115,000 on Monday night — down from 186,657 in 2016 and lower than 2012′s 121,503 and 2008′s 119,207.Of those Iowans who bundled up in layers, donned their warmest coats and gave little thought to staying home, and with roughly 96 percent of the expected votes tallied, 51 percent of caucus-goers selected Trump, 21 percent picked Florida Gov. Ron DeSantis and 19 percent backed Haley, a revealing glimpse at Republican voters’ choices in this first contest.
