That's a perfectly legitimate argument to make. I disagree because we've seen the result of politicians making our fiscal policy. We've had whipsawing tax policies, a ridiculously complex tax code, huge deficits and a lot of debt all because they're looking at every decision in the light of an election no more than two years hence.
I don't want those forces dictating policy in an area they know even less about.
Regardless, an honest debate would be fine but what does it tell you when Fed opponents aren't willing to say what their real objective is and instead hide behind the audit BS?
It tells me they know their argument is a loser.
They used this artifice because at the time it was proposed, straight talk about the Fed was received about the same as talk about Area 51. Things have changed enormously since; the issue remains the same, either we the people should have political control over the institution or it should not act as a quasi-public body.
