Well, he didn't resign from Washington, but he did from Missouri. For those of you not familiar with the situation, I worked on a documentary project awhile back that followed a 2004 congressional race between Jeff Smith and Russ Carnahan in Missouri. I handled all the graphics and design for the marketing material as well as some other stuff. Jeff wound up losing this race with Carnahan, but eventually went on to win a seat in the Missouri state senate. This was largely possible because of the success of the "Can Mr. Smith Get To Washington Anymore?" documentary. After the movie, there wasn't to many people that didn't know who Jeff Smith was.
The movie portrayed Jeff as a very charismatic, for-the-people type of guy. You couldn't resist liking him after you met him. Unfortunately, looks can be a little deceiving, because apparently Jeff was a very bad guy.
