There's an interesting piece on MSNBC.com called Where Do They Stand? It's a 17-part comparison of where Bush and Kerry stand on various issues of importance in the election. You choose whose position you agree with more, and when you get to the end I think something is supposed to happen ... but I get a javascript error, so nothing does.
The one thing I think is flawed about this piece is that it is clearly written from an anti-Bush stance. Not that I mind, of course. But it is not as unbiased as I think it should be.
