> you're attempting to evade the central point by changing the argument to a typical Republican/Democratic slugfest.

I wasn't intending to.

> I don't care about the merits of Congressional prerogatives here, which is an entirely secondary point. The point is that the Founding Fathers believed that Congress would defend its own prerogatives against the executive. This has been proven false.... Congress is driven by the needs of the political parties who happen to be running it at the time, not as an institution in itself.

Got it, this is a better explanation and I think I agree with it.
