[Yo-Yo]

The Supremes, especially in the 1930s in upholding much of Roosvelt's Raw Deal, did stretch the interstate commerce clause as much as they did in finding the right to privacy in the first amendment.

But they did not find that congress can regulate anything and everything just because they want to.

[Straight Vermonter]

They came pretty damn close to it.

Even if activity be local and though it may not be regarded as commerce, it may still, whatever its nature, be reached by Congress if it exerts a substantial economic effect on interstate commerce, and this irrespective of whether such effect is what might at some earlier time be defined as "direct" or "indirect."
