Just a quick thought: when you watch Tuesday night’s debate, see who is in the middle.
Romney has always been in the middle; he’s the frontrunner. When Perry got top billing, he was next to him. Then it was Bachmann, and at the corners were the fringes. Now Cain is moving up. Look to see if the debate organizers play up this horse-race aspect of the race on Tuesday, and put him in the center with Romney. See if they emphasize the current frontrunners, or if they try to give equal billing to everyone. The other debates have consistently pitted number one versus number two, but maybe this will be the exception. We’ll see.
