Clinton has enjoyed strong, steady leads in polling in many of the states that have been closely contested in recent elections like Ohio, Pennsylvania, and Virginia.

But the race in Iowa, another recent perennial toss-up, has remained very close in the polls.

O’Malley was asked Sunday why he thinks Clinton has been able to pull away from Trump in other perennial battleground states but not Iowa.

“I’m not exactly sure, but it’s my sense that people in Iowa like to make up their minds toward the end of the process, not at the beginning of it,” O’Malley said. “They’re very savvy. The caucuses make Iowa voters very savvy. That means that Iowa people like to see the race play out before they make up their minds.”

When more Iowans start tuning into the presidential race, O’Malley said he thinks those voters will be drawn to Clinton.

“When Hillary Clinton speaks to wages, to the issues like affordable college that matter around people’s kitchen table, I believe that she’s going to start pulling away here in Iowa,” O’Malley said. “And that’s what I’m going to do everything in my power to help her do.”

During his remarks, O’Malley unleashed criticisms of Iowa Gov. Terry Branstad as well as Trump.
