I pretty much agree with you, although Deroy makes some good points. I would have to say that Bush got the number one thing right, but he was a lukewarm conservative at best and his second term has been a disaster for the GOP.
About as fair and accurate an assessment as one could make.
One quibble, though. I wouldn't ascribe the turmoil in the GOP solely to Bush. The actions of the GOP majority and its leadership in Congress did much to foul the nest.
I recall our incessantly having to make excuses for them -- well, they don't really have a majority...well, there are some political realities they have to deal with, etc.
Next time, we should know better. Be merciless toward our elected officials. Hold their feet to the fire. And, if necessary, burn them in the primary.
