You say that as if it were a bad thing, I say if gives more pull from the States and the citizens toward Federal Government that way.
You want California, New York, and Illinois to withhold the fair tax they have collected until Bush withdraws from Iraq because they disagree with his policies? You want Massachusetts and Oregon to withhold their taxes from the federal government until it passes a federal gay marriage act? You want Arizona and New Mexico to withhold their taxes until illegal immigrants are allowed to receive the fair tax credit?
It's a recipe for disaster.
