Sarah Jones at PolticusUSA makes the case that Republican blocking of Obama appointees keeps Bush appointees in place and that is what can be wrecking havoc.
Lois Lerner, "who let slip at an American Bar Association meeting on Friday that, between 2010 and 2012, conservative nonprofit groups were improperly scrutinized by the IRS", is the person who drew attention to this "scandal". She is also the IRS Director of Exempt Organizations.
Lerner gave an opening statement before yet another House Committee Wednesday morning, in a hearing on the allegations that the IRS targeted conservative groups for political reasons. Ms. Lerner said, before pleading the fifth, "I have not done anything wrong. I have not broken any laws. I have not violated any IRS rules or regulations, and I have not provided false information to this or any other congressional committee," Lerner said. "Because I am asserting my right not to testify, I know that some people will assume that I have done something wrong. I have not."
…Republicans are trying to insinuate that Lerner covered up for the Obama administration and that's why she's pleading the fifth. They can't possibly know why she is pleading the fifth; the most logical reason is that given the DOJ opening a criminal investigation into the matter, her attorney advised her to shut it.
But if she has any political persuasion, it would seem to be Republican, based on her appointment by the Bush administration (infamous for politicizing government)…
What I've taken from all of these scandals so far is that by Republicans refusing to allow Obama his own nominees, they've saddled him with their appointees, who may or may not have an agenda and may or may not be utterly incompetent. That's a nifty game.
