PROTECT THE CONSTITUTION: Require each bill to identify the specific provision of the Constitution that gives Congress the power to do what the bill does.
So, people really think that it will help to protect the Constitution to write "Article 1, Section 8, Clause 3" on every bill? The court has historically interpreted the commerce clause in such a way that everything is justified by it. The hard part is getting the court to stop doing that, not making Congresspeople write some extra stuff on the bill.
Companies disclose if a single customer represents even 10% of their revenues, because it's a risk factor.
"Let's spend more money on the armed forces and post office, to make the portion that comes under Clause 3 appear smaller."
A lawyer I spoke to told me that there's a question regarding federal law on the bar exam every single year, asking "From where is the power to create X law derived in the Constitution?" It's a different law every year, but the answer is always the same: "The commerce clause."
