- Hillary Clinton will return to Iowa for events on October 29
- Every trip Clinton, the frontrunner for the Democratic nomination in 2016, makes to Iowa is seen through a presidential lens
- Clinton was in Iowa last September for the 37th annual - and final - Iowa Steak Fry
Washington (CNN) -- Hillary Clinton is headed back to Iowa on October 29, according to a Democratic source with knowledge of the trip.
The former first lady's visit comes just a little more than a month since she returned to Iowa after a six year hiatus. Clinton stumped for Bruce Braley, Iowa's Democratic Senate nominee, and other Iowa Democrats at the 37th annual - and final - Harkin Steak Fry in September. She had last visited the state in 2008.

A number of big name Democrats have come to Iowa to help Braley. Vice President Joe Biden will stump for the Senate hopeful at an event in Davenport on Monday and first lady Michelle Obama stumped for him earlier this week.
Any visit Clinton makes to Iowa - the crucially important first-in-the-nation caucus state - is immediately seen through the lens of 2016 politics given that the former first lady is widely seen as the Democratic frontrunner for president and has admitted that she is considering a run.
Clinton's October visit to stump for Democrats in Iowa comes near the end of her prolonged push for Democrats across the country. Clinton has headlined political events in California, Colorado, Michigan, Kentucky, Nevada, Pennsylvania, Illinois and Florida in the last month. And is expected to return to New Hampshire and Georgia by election day.
While all of these events have been for Democrats seeking to win in November, the campaigning is also a way for Clinton to satisfy Democrats who expect their potential future presidential nominee to help the party in the years before the run.
By election day, Clinton is expected to visit over 15 states in her midterm push.
