I don't want to take the time to look the whole thing up right now, but if I'm not mistaken I believe that Paul Ryan's plan, which is supported by Romney, gives the biggest tax cut to the top 1%. I think it's a bit naive to think some of that money isn't going to go to political campaigns to get themselves further tax cuts.
Not to mention Obama has, in fact, supported continuing tax cuts for those making less than 250,000K per year. I would say that is letting a person keep more of their own money.
As far as Capital Gains... Romney's plan isn't bad. I think I could get behind elimination of CG for those making less than 250,000K.
