The comparison is utter BS.
For one, this had nothing to do with the president.
For two, this appears to have more to do with various difficulties in implementing the tax code regarding non-profits, particularly with the political non-exemption issue and the explosion of "political" non-profits after the Citizens United ruling, than an actual conspiracy to undercut conservatives. That it did was more a byproduct rather than the actual intention.
For three, the IRS was the one to blow the whistle on itself. They realized that this had been an issue, and had been revising their evaluation process in an effort to make it more impartial. Ooh! Such a big conspiracy!
For four, not one conservative group actually lost its non-profit status as a result of this. So, it sounds like a whole much of crying about milk that never was even spilt.
