Obama vs. Romney on tax rates: As you can see, rates are largely the same—except for the nation’s richest and poorest. The poor would pay almost twice as much in taxes under Romney’s plan; meanwhile, the very richest in the country would be forced to cough up about 10% more of their income under Obama. The net effect? In short, Romney’s plan would reduce federal revenues to about 17% of GDP—down .9% from where they are now. Obama’s budget would raise revenues 19.2%, with most of that money coming from those making over $250,000 a year (Graphic and data courtesy of The Washington Post / Tax Policy Center).
