Just search the site for one of the several threads pertaining to the US Attorney brouhaha (I'd recommend the search term "Goodling" and/or "McKay." That should get you going.
Frankly, I don't care WHY they were dismissed - it's irrelevant under the law. As I indicated, the US Attorneys are political appointees and not career civil servants, which means that they can be dismissed without stated cause. I think the GWB administration royally screwed up by making any comment on their dismissal at all. I approved of Sampson and Goodling leaving the DOJ, and I called for AG Gonzales' resignation on the grounds that he was either knowledgeable of what was going on and corrupt, or ignorant of the goings-on and therefore inept.
I also think that Congress should revisit the legislation covering the Attorney General being able to appoint a temporary US Attorney to fill a vacancy and either put some major restrictions on the use of such power, or remove it altogether. Congress should retain confirmation power regarding the appointment of full-time US Attorneys, no "ifs, ands or buts" about it. But from a Constitutional standpoint, Congress passed the legislation delegating such authority TO the Attorney General, which gives the law authority until/unless challenged at SCOTUS or repealed via Congress.
BTW, for someone claiming not to want to have hate and malice in the discussion, you came out of the gate making accusations that I somehow supported positions I do not. If you start out that confrontational, you're going to get it back in spades.
