On my other blog I posted my idea for a new congressional agency, please give it a read. Small preview:
The Congressional Constitution Office would be a mandatory part of the legislative process. All legislation that made it through the House or Senate would require an addendum from the CCO analyzing exactly where the US Constitution grants the legislative branch of government the power to pass the particular legislation (please see the 10th amendment). Rule changes stipulating that bills must be constrained to one similar topic would be required to make this work, for example no social program spending can be combined with a military appropriations bill, and would provide the side benefit of making the legislative sausage-making process more transparent.
