It's time for a Republican debate on the Constitution

So what about the current generation? There is so much to debate about the Constitution—war powers, gay marriage, birthright citizenship, the gold standard, the role of the vice president, campaign funding. One could go on. Holding a debate centered on the Constitution could bring a coherence to the campaign.

And also some fun. One of the big issues this year is the Commerce Clause, one of the grounds on which the Obama administration is claiming the right to have passed ObamaCare. The clause gives Congress the power to “regulate Commerce with foreign Nations, and among the several States, and with the Indian tribes.” Do the candidates who reckon that Congress can use this clause to reach into a state to regulate economic activity there also reckon that they can reach into foreign nations and the Indian tribes and regulate their commerce, too?
