I personally think Bush is trying to make trouble for Hillary. How is she suppose to explain away to her wackado base that her husband's new best friend is their mortal enemy?
I would have trashed Clinton using the same agencies that Clinton has used to abuse the GOP. I would have dumped all of the files from the EPA, Commerce, Interior, etc requested in the many suits by Judicial Watch and I would have set the IG upon the IRS to determine once and for all how every right wing publication and think thank got audited in a 5 year period. I would have debriefed all of the Secret Service and leaked it to the Washington Post. And I would have dumped every single person in the Federal government appointed by the Clintons who couldn't prove that they had voted for me. And I would have immediately put out a list of all of the last minute expenditures, executive orders, personnel appointments and anything else done in the middle of Clintons last night to the public right before I reversed all of them.
But, like I said, Bush is a better person than I am.
