Hello Borges,
You answered your own question.
Moreover, below is more info for you to back up what I said. You can dismiss it if you wish, but Rush Limbaugh read another article from the LA Times (I can't find it on Yahoo) where the script writer said they wanted to prop up Clinton's image.
"But Bill Clinton is the first president to spawn movies that feature fictional presidents functioning as his stand-ins, movies made by directors fighting to define, and redefine, his image.....Air Force One" is a fantasy of what it might take for President Clinton to become all things to all people. The movie's Clinton stand-in, President James Marshall (Harrison Ford, appropriately displaying the facial mobility of Mount Rushmore), is a leader who defies his timid advisors in his efforts to set policies against injustice and tyranny and is willing to take on Congress to enforce those policies. But this is a fantasy designed to silence Clinton's conservative critics, so not only is Jim Marshall a dedicated family man, but he's a Vietnam War hero to boot. There's a combo you can't beat, a guy who knows how to kill a Commie and keep his pecker in his pocket.
Further, Clinton even admitted he had a role in the movie, including asking Glenn Close to play the Vice President:
Clinton Had 'Role' In 'Air Force One' Movie
Also, Stephen Hunter said about the film; This is the one into which Clinton should have had himself inserted!
Well, he did.
The fictional President played by Ford in the film had nothing in common with Bill Clinton at all. FDR's populism inspired a lot of movies as well but that doesn't make 'Mr. Smith Goes to Washington' a veiled portrait of him.
