Nope. Even a farmer growing for his own consumption 'affects commerce' according to the SCOTUS and is subject to federal authority through the "Commerce Clause"
Yes, in fact, the Commerce Clause is the excuse they use for every Socialist move that the government uses. They even used that clause to justify Medicare, and will use it for Obama's "health care provisions.
The Constitution of the US has been trashed by the SCOTUS, Congress, AND the last several presidents.
In fact, Article 1 section 8 gives no such power for Congress to enact such laws, but the activist SCOTUS has REWRITTEN, in effect, A1 S8. They have committed TREASON, but who can hold them accountable, as the highest court in the land?
