My 2c about your GWB study: Your "he's corrupt" propaganda looks like propaganda, and not solid evidence, because right from its creation, the CIA has kind of melded with the Bush family and has, historically, spent a lot of time and money covering for them and scrubbing conclusive evidence of any corruption. They don't do that with any material that is favorable.
Yeah, that's more like it!
So it's relevant to PAY FOR PLAY, and various other prohibited means of remuneration for government officials.
