We’re seeing lots of good pieces which point out that many of the claims the Republicans are making about their tax plan are not true, that the plan favors the rich at the expense of the middle. But today I want to make another point about the plan, one that doesn’t seem to be getting the attention it merits. You see, it’s not just that the Republican plan helps the rich and hurts the middle. Those distributive consequences are real, and they matter, but this goes deeper than that. The Republican plan specifically targets liberal and left-leaning groups in the country for tax increases. It is an assault on the political neutrality of the tax system.
