Last year I debated a libertarian about the EPA.  I didn't even have to make my case!  As you can see in the somewhat long discussion thread over at Busta's site, there just wasn't much I needed to do.  My opponent made all kinds of verifiably false claims.  The thing with the light bulbs.  I knew the light bulbs were going to come up and I was prepared for it!
