Bush can't be compared to Reagan. W has never worked a day in his life nor provided for himself and his family on his own. He had no career before politics and doesn't even give lip service to the Constitution.
If Bush is going to make Reagan look like a liberal, he sure is off to a slow start.
Of course, Clinton was full of sh!t 99% of the time, but once his first two years were an utter failure he decided that his own career was more important than his liberal principles and toed the Republican Party line for the most part.
The most lasting impacts of these presidents are their Supreme Court appointments, and Reagan's weren't much better than anyone else's.
