There were tons of Tea Party groups that applied for 501(c)(3) non-profit status when they had no business doing so. Some were intentionally trying to cheat the system, while others were too naive to know any better. Since 2009, more than 3,500 affiliates of the Tea Party Patriots have popped up, and many of those applied for non-profit status. Some of those people were business/non-profit newbies that just wanted to jump on the Tea Party bandwagon that was booming. Others were intentionally looking for ways to avoid taxes while supporting their political party.
With that being said, there are probably just as many liberal leaning political organizations that have applied for non-profit status, yet should not be granted non-profit status due to their level of political involvement. I can give Obama a pass for only calling out conservative groups, as he is, afterall, a politician who is a Democrat. The I.R.S., on the other hand, should have never enforced their authority in such a way so as to target one political party and not the other. If you've got a known problem with these political activist groups and you want to target them for audit, that's fine, but don't target one political party and not the other.
