If forced to choose between Bush and Clinton, he chooses Bubba.
President Clinton... I certainly had my problems with him. But what he did, in terms of perjury and obstruction was bad but it was not destructive of the very systemic foundations of our country.
What Barr isn't seeing is that Clinton had his party in control of Congress for only two years, whereas Bush had his party in control for six. Give Clinton six years of a Democratic Congress, and there'd have been Wacos and Elian raids all over the place.
It's not evidence of the intrinsic good of Clinton and the intrinsic bad of Bush, but rather of how much liberty dies when government can "get things done" without the intrinsic good of gridlock.
