As I’ve repeatedly written since this came to light, the IRS is supposed to be giving close scrutiny to all entities seeking 501(c) status, and that they are supposed to be revoking that status if they find inappropriate political activity.
The problem is that the TIGTA found that the IRS used inappropriate criteria in weeding out the entities that it wanted to look at more closely - because the IRS has limited time/funds/personnel to examine these entities closely.
If anything, this reinforces the need for the IRS to examine all entities seeking nonprofit status under 501(c) - whether it’s (c)(3) or (c)(4) or any of the other classifications under 501. There are far too many groups that are playing fast and loose with the rules and just flat out ignoring the prohibition against political activities.
