While not a Repub fan, I gotta say the hub-bub about how much Federal tax Mitt pays is BS. The vast majority of Americans don't pay 15% of their AGI in Federal Tax. With all the deductions for houses, kids, whatever, most Americans are below this rate. http://www.taxfoundation.org/news/show/250.html#table8
Yea, yea, theres SS/Medicare but that was not caluclated in Mitt's returns either. So as ususal Americans are about their high taxes. Not!
You are never going to get what is needed to get a more balanced budget by trying to milk the top 2%. A more reasonable approach would be to let ALL Bush era tax cuts expire, bump up the capital gains tax, and remove the SS cap on taxes.
