As a result of the dissatisfaction with the GOP presidential field, CBS News notes that voters "are waiting until the last minute to determine for whom to award their ballot."
"In Iowa, nearly half of caucus-goers decided in the last few days. Of those voters, two in 10 made their decision on Election Day. In New Hampshire, 46 percent of Republican primary voters decided in the last few days, of which 21 percent made up their mind on the last day. In South Carolina, roughly half of Republican primary voters settled on a choice in the last few days before the election, while in the Florida, a quarter of Republican voters were late deciders."
