The 2008 Republican primary campaign was quiet today, probably because the candidates are prepping for tomorrow's CNN / YouTube presidential debate. The fun starts at 8 p.m. Wednesday evening. Look for the Giuliani-Romney spat to dominate most of the opening round of questions. Look for McCain to discuss his Thanksgiving trip to Iraq. Something tells me the debate will be great fun for people who like attack politics (in other words, people like me). Rudy probably will be the biggest target, though Romney may take a lot of punches as well. Still, I have two questions: How much time will go by before Anderson Cooper gets around to asking Tancredo, Hunter, or Paul a question? (Forty minutes sounds about right.) And will Billiam the Snowman make a return appearance?
