A new poll conducted by Iowa pollster J. Ann Selzer has revealed that former President Donald Trump has a 20-point lead over his nearest rival, Ron DeSantis, among likely Iowa Republican caucusgoers. 71 percent of Trump's supporters believe what he says is true, and 62 percent of the respondents plan to back him in the primary. Trump has an advantage over other sources of information, and the poll results show that he has an early advantage in the first nominating contest.
