Don't expect much from the IRS. I spent 33 years there and there are only a relative handful of agents assigned to Tax Exempt organizations and most of what they check are large charitable trusts.
You would almost have to file an actual complaint citing some instance in which an exempt organization violated its terms by some improper political activity.
