LOL, he is probably partly not releasing them just to get a kick to see the progressives get all wound up over a non-issue. The Obama thugs have already instructed the IRS to go over those years with a fine tooth comb and obviously did not find anything.
What I find really amazing is Romney most assuredly paid more in taxes than any of us here may ever even come close to making in our entire lifetimes, yet people are quetioning if he paid his fair share? Very clear the socialist leanings of some!
