Since I tend to enjoy your thought process:
Why are you so down on Romney - in another thread, even ranking him below McCain?
I moved Romney back above McCain now. He seems to be getting traction in South Carolina and has steady leads in Iowa and New Hampshire. The problem with Romney remains the same problem as always - electability. It will play a factor, give it time.
It might happen, it might not. It's very hard to tell. Part of it may depend on media reaction.
He's not anymore. Thompson's probably done, but for some reason I give him a slight shot.
McCain's scenario depends on a win in New Hampshire, plain and simple.
Richardson scenario is dependent on him finishing second in Iowa, an opportunity that may be slipping away.
