Howard Dean's visit to Renton this weekend was really only the beginning of what is sure to be a lively seven weeks until the election. The first celebrity deathmatch pitting Obama versus McCain on national TV is still 11 days away. But if you want to wet your chops with a little political debate action this week, you're in luck. Our own homestate smackdown will be broadcast on KOMO-4 this Saturday, Sept. 20, at 9 p.m. It's the first of five scheduled debates, so we suggest you get to work on the rules for your Gregoire v. Rossi drinking game. We'll start you off: anyone mentions the viaduct, you drink.
