He may be from Flint, Mich. but Michael Moore is an Iowa boy at heart.

“I love Iowa,” Moore said. “I always find myself coming back here.”

Moore has been described as “Garrison Keillor with a political edge.” His films are cult favorites, his TV show is revered and he makes Newt Gingrich cower behind security guards.

Michael “The Man” Moore will be at Big Table Books tomorrow at 4 p.m. to sign copies of his new book, “Downsize This: Random Threats from an Unarmed American.”

Moore’s affection for Iowa is evident in “Downsize This.” Chapter after chapter mentions people, towns, events and restaurants from the Hawkeye State.

Most importantly, it was in Des Moines where Moore’s suspicions about Steve Forbes were confirmed. Chapter 14 of Downsize This, titled “Steve Forbes Was an Alien,” details an interview with a Forbes aide about the origins of the former presidential candidate.

“I think it’s time we bring the’ X-Files’ in on this one,” Moore said.

Before his alien sightings, Moore received national recognition in 1989 for Roger & Me, the largest-grossing documentary film of all time.

The film chronicled Moore’s quest to find General Motors Chairman Roger Smith. Moore wanted to convince Smith to visit Flint and witness the devastation wrought by GM plant shutdowns.

Moore is also the creator and host of the award-winning television series “TV Nation.”

The series has been called “a kamikaze ’60 Minutes,'” with Moore staging and videotaping events all over America.

Although the show is temporarily on hiatus, Moore has been working hard to keep the satire alive.

“We’re trying to get it back on the air,” Moore said. “Meanwhile, Comedy Central is going to rerun all the old episodes.”

Moore has risen to the top of the entertainment world by fighting corporate America. But his true passion is reserved for the millions of Americans who have lost their jobs because of downsized companies.

“I hear the stories everywhere I go,” Moore said. “People who’ve been fired, been put out on the streets, people who are working overtime at $4.85 an hour to try and pay the cable bill. They’ve all lost the American dream.”

“There are so many sad stories,” Moore added. “I’m just glad I can listen to them.”

He does more than just listen to the stories. He publishes them. Roger & Me, “Downsize This” and “TV Nation” all reveal the problems of American society.

Moore tells these stories because he thinks people can learn from them.

“I try to create change wherever I can,” Moore said. “People using their individual powers can create a lot of good.”

Moore’s booksigning at Big Table is free and open to the public.

Moore will also be appearing at the Iowa Shares benefit “An Evening with Michael Moore” at Hoover High School Auditorium in Des Moines at 7 p.m. Singer/humorist Dan Hunter will be opening for Moore. Tickets are $16 and are available at Big Table Books, Java Joe’s Coffeehouse in Des Moines or they can be purchased at the door.
