What if the election came down to one specific man and his one vote? That's what Swing Vote is all about. I'm not sure if the explanation of how it happened is correct, but it's plausible, and the movie is amusing and funny.
Kevin Costner is a good-for-nothing good old boy in New Mexico, and it's his vote that matters. Imagine the kind of scheming the two candidates will go through to get that one vote.
I liked just about everybody in the movie, even the evil ones. Sure, they're all pretty much cliches, but when you have Kelsey Grammer, Stanley Tucci, Dennis Hopper, and Nathan Lane playing the parts, it's quality work. Some people don't like Kevin Costner, but I do, and he can be charming even in a role like this one. And Madeline Carroll steals just about every scene she's in.
If you're fed up with the election campaign and want some light entertainment, you could do worse. It's a comedy, after all, and everything works out for the best. Just as it does in another political movie I recommend for these trying times.
