Via Kevin Drum:
As the chart [above] shows, conservatives are right to believe that Romney isn’t to be trusted. Sure, he lowers tax rates on millionaires by 9 percentage points, and you may think that’s a pretty sweet deal for the rich. But come on. Newt Gingrich would lower them by 24 percentage points. (No, that’s not a typo.) Rick Perry lowers them by 20 percentage points. Herman Cain lowers them by 15 points. Frankly, Romney is hardly even trying here.
Also, except for 9-9-9, all these plans show no or little tax cut for the lowest marginal rates. Stay classy!
