Funny how the GOP leaders now admit that increasing revenue is necessary, but choke on raising the top marginal rate. Assuming the same increase in revenue, what's the difference? Well, besides the Grover Norquist promise, the difference is that they're lying about the loopholes, and hope their base will still be able to circumvent them. Raising the marginal rate means an increased likelihood that "the rich" will actually end up paying somewhat more. Can't have that...
