Now we are getting somewhere. I am more interested in how you come to the opinion he's abusing anything. I can read or listen to the talking heads all week. So, in your humble opinion, why is this an abuse of power and how would you personally fix it?
Americans overwhelmingly believe that those who do a good job deserve reward and those who do a bad job deserve firing. While not written into any specific laws, it's, verifiably, a tenet of the American psyche. We hate ass-kissers, especially those who reap rewards for nothing more than kissing ass. Why? Because we have a general affinity to work ethic and competency over nepotism.
When the President/Attorney General/the Attorney General's secretary/Karl Rove/Dick Cheney (who knows? the story changes daily and no one seems to have known anything about the firings) chose to fire these U.S. Attorneys, the American people didn't care... because they were under the impression that they were fired for not doing their jobs... as the Attorney General cited "performance reasons."
But, that turns out to not be the case. The Attorney General (at the behest of whom?) lied to us and lied about them. They were fired for doing their job. Unfortunately, doing their job meant doing things that sometimes hurt the political power of those above them. They were fired so that people who wouldn't do their job (and, possibly, would skip or gloss over the legal abuses of a Party in power).
That is an abuse of power in my eyes.
