Consider all the passes GWB took on opportunities to prosecute Clinton cronies. The skating of Sandy Pants Berger for stealing documents from the national archives was typical, not exceptional.
Then there's all the public kissing of the Clintons ranging from GWB's appearance at the opening of the presidential library in Little Rock to Bill Clinton and Papa Bush's fundraising for disaster victims.
I've come to the sad conclusion that the Bush and Clinton Dynasties may differ on methodology, but they are on the same side.
I don't quite follow your reasoning unless you are talking about Jeb 4-8 years from now, if so I really believe that it would flop, due to the public becoming absolutely sick of the Bush/Clinton dynasty.
I didn't agree with the author of this piece at all that GWB might actually do something with any info that he may be privy to because as you pointed out, he has had countless chances to do so and has to date not only done nothing but seems to have quashed anybody elses efforts to do anything.
The way that both Bushes have buddied up to the likes of Clinton and Ted Kennedy absolutely turns my stomach. Both Kennedy and the Clintons are contemptable.
