Like the "gut feeling" we had that GWB's compassionate conservatism was more conservative than compassionate? No, it's not a gut feeling. It's a delusion.
GWB HAS disappointed me on a number of accounts (Iraq invasion lack of post-planning, failure to really fight the 'Rats 24/7 instead of just before election time - worked in 2002-2004-failed miserably in 2006)
But, GWB, for all his Texs talk, comes from a genteel upper-crust family.
Rudy, OTOH grew up on the streets of Brooklyn and is a self-made man. If you don't think that there is a world of difference in how they will approach the opposition (ie. Rudy will use brass knuckles where Dubya would have used a slap), then I don't think you're a good judge of character....
