Sanders will speak in Iowa City on Aug. 31 about his new book, "Bernie Sanders: Guide to Political Revolution," the Iowa City Press-Citizen reported.

The co-owner of Prairie Lights bookstore, Jan Weissmiller, said before Sanders launched his 2016 bid for president that Sanders came to Iowa City to read from his book "The Speech: A Historic Filibuster on Corporate Greed and The Decline of Our Middle Class."

"We had three days to promote that event and we got 150 people to show up," Weissmiller said.

More people are expected for the August visit, as Sanders will speak at an auditorium.

At a January 2016 rally at the University of Iowa's Field House, Sanders drew a crowd of between 3,900 and 5,000 people, according to the Press-Citizen.

Trips by politicians to Iowa are always seen through the lens of presidential politics.

Sanders would be 79 in 2020. Some have thought his age might prevent another run for the White House, but the race for the Democratic nomination at this point looks wide open.
