It is, in my opinion, that after appointment, USA's should be apolitical. Maybe you disagree with me on that point and the attorneys are political hacks.. I'll quote Bob Dole (1993) when he spoke about Clinton's pro forma change of all 93 USAs: "The American people deserve a Justice Department that takes a back seat to politics and one that functions efficiently."
I really don't understand how one can completely divorce politics form a political appointment, cause thats what this position is. Every single person who took this job understands this.
Personally, I agree with you that justice should trump politics, but I'm not going to stand in the way of something that the constitution allows, distasteful or not. This of course assumes that these people were dumped for political reasons, which I don't believe. In fact its on record that 3 of these attorneys had complaints from both republicans and democrats regarding their performance. The rules are the rules for a reason, and we don't get to change them when they don't go our way.
