|Such a decision would roil the country, would likely plunge Washington into a new round of partisan warfare, and could even imperil Obama's domestic priorities, including health care and energy reform.|
I think this is totally wrong. First, we've already achieved essentially-maximal partisan warfare, whereby Republicans vote in lock-step against whatever the Democrats try to do. And it is not like the various apparatachiks (no, I can't spell that) to the two parties behave civilly when appearing on TV and radio. So how in the hell would this imperil any of Obama's priorities? Sure, Hannity will have something new to bitch about, but it is not like the inability of the news media to cover more than one story at a time will prevent the US Congress from putting legislation through the sausage grinder.
I suppose one could argue that this could be damaging to Obama's priorities if there's a vast anti-Obama backlash should the AG appoint a prosecutor, which would then give some 'centrist' Senators cover to vote against Obama... BUT they already do that! There are plenty of 'centrists' who are going to require a lot of cajoling (read: legal bribing) before they get on board with various pieces of legislation. And there are plenty of Republican Senators from states Obama carried who haven't even attempted to move left after '08 (e.g. North Carolina, Indiana, Maine). So while the newsmedia may be derailed in their ability to spout uninformed opinions on health care because they are too busy spouting uninformed opinions on Bush's war crimes, I think the Senate is more than capable of multi-tasking and screwing up many pieces of legislation no matter what the AG is doing.
