Yes. Bush seemed more naive and unpresidential then compared to now, when he's arrogant and wrong on many issues.
I really resented Bush when he "won" in 2000 without a majority PV, but when he was re-elected I didn't suffer any blues at all since the EV and PV for both he and Kerry were pretty "fair"
I wouldn't dwell on the past. The important thing now is to nominate a Democrat who can win in 2008!
Furthermore, its important to concentrate our efforts regaining control of Congress, governor's mansions and state legislatures
