Your suggestion has a lot of merit...the IRS can easily do that, in fact, for executive office appointees they do it routinely, with a permission slip to do it signed by the applicant. The report comes back: all returns filed, no taxes due and owing.
After he does that, all he has to do is say, well, Obama, I showed me mine now show me your college/birth/passport records.
I really wish the campaign would pick this idea up. It’s perfect. Unless, of course, he didn’t pay taxes one year. Otherwise, Dingy Harry has given him the perfect out for this BS tactic Ovomit is using to detract from his record.
