Well if Fred Thompson doesn't declare pretty soon, he's going to find out the primary happened without him if this political leapfrogging to be first continues at this pace. Which might not be such a bad thing. The more he talks, the more he sounds like Bush. Watch for yourself.
He's got the Bush role internalized, right down to the vaguely butchered language. If we leave Iraq, the whole region "will become nuclearized?" Fred is the new Bush, only old, and with jowls.
I'm left with two impressions. Thompson is a terrible off the cuff public speaker and the more weight he loses, the older and somewhat sickly he looks.
