Former Secretary of State Hillary Clinton enjoys a lead of 29 percentage points over Sen. Bernie Sanders (I-VT) in Iowa, according to a poll released by Loras College on Friday.

The poll showed support for Clinton among likely Democratic caucusgoers at 59 percent. Sanders claimed the support of 30 percent of respondents, and support for former Maryland Gov. Martin O’Malley stood at 7 percent. This represents only a slight change since Loras College’s December poll, which showed Clinton at 59 percent and Sanders at 27 percent.

The Loras College poll deviates significantly from most Iowa polling, which has shown a tight race amid a surge in Sanders support that, according to some surveys, has allowed him to surpass Clinton.

Pollsters surveyed 500 likely Democratic caucusgoers by live telephone interview from Jan. 13-18. It had a margin of error of 4.4 percentage points.
