I don't think they did it out of political bias. As I read what happened, they had criteria for selecting applications for review. At some point, they had this big influx of applications for 501(c)(4) status and the suspicion index was high because of concern that some of them might not be legit and were just using the name to try to gin up some dough. And so they were given special attention, then the criteria changed over time.
I certainly understand that the GOP wants to if nothing else mollify the TP base over this. I just don't want people to jump the gun that there was some sort of concerted effort by a political arm of the bureaucracy to go after a rival group.
As I say, if there were some indication their applications were actually denied at some sort of statistically significant disparity, then that would be strong evidence of it. But no one is saying that.
That they used the names of "tea party" or "patriot" or similar things is known. But that does not mean that the people that did this or okayed it were particularly against the "tea party" or the "patriots."
That is the disconnect that everyone needs to keep in mind at this point. As I say, I am sure Issa & Co. will try to find proof that it was bias-motivated. But right now there is no reason to think that.
