Gov. Scott Walker's first visit to Iowa as a presidential candidate may have padded his lead in the state among Republican caucus-goers, according to the latest poll from Monmouth University.
The poll of 452 likely Republican caucus-goers conducted over the weekend found 22 percent supported Walker as their first choice, and 13 percent supported him as their second choice.
Walker's support went from 19 percent in calls made Thursday and Friday to 25 percent in calls made Saturday and Sunday.
Walker also had the highest favorable (73 percent) and lowest unfavorable (9 percent) rating among 17 declared and likely candidates. Only 18 percent said they had no opinion of Walker, or about half of what national polls have been showing about how well the American public knows Walker.
Walker's first campaign visit to the must-win state took him through 11 cities from Davenport and Dubuque on the eastern border, to Council Bluffs and Sioux City on the western border. At almost every stop he drew between 200 to 300 people.
The poll found real estate tycoon Donald Trump received the second most support with 13 percent. The poll found no change in Trump's support over the weekend, even as he came under fire Saturday for remarks disparaging 2008 Republican presidential nominee Sen. John McCain at an evangelical summit in Ames, Iowa.
