The Republican Study Committee was founded by Republicans who thought the mainstream of their party was too moderate. Proposals that go beyond what is politically feasible is part of their mission, because they want to change the boundaries of what is feasible.

(For example, right now the committee’s Web page links to an op-ed advocating a flat 15% income tax. The President—any President, of either party—will sign a flat income tax into law some time after the Air Force trades its fighter jets for flying pigs.)
