Yeah, but it's related. If some kind of in-state activity has a substantial effect on the interstate commerce that Congress is constitutionally regulating, Congress has the power, under the Necessary and Proper Clause, to pass legislation controlling that activity.
Congress regulates interstate airlines. Even though a private pilot is flying from one part of his state to another, Congress may also regulate his activities if they interfere with interstate airline traffic.
Of do you trhink they're not allowed to do that?
Nonsense. First of all, the passing of laws that touch on things that may AFFECT i.s.c. is immoral, corrupt, evil, horrible, f*&^ing liberal nonsense. As has been pointed out by every true conservative for 1 billion years (G. Gordon Liddy almost every day, in fact) regulating everything that may AFFECT i.s.c. is in fact, license to regualate EVERYTHING ALL THE TIME. EVERYTHING ALL THE TIME, might possibly affect interstate commerce. When the horrible liberal scum sucking pieces of sub human filth on the Sup. Court were passing FDR's unconstitutinoal laws, they noted (in the 'Sick Chicken' case) that Farmer Joe growing his own chickens on his own farm that were meant to be sold only LOCALLY could, possibly affect i.s.c. because his customers might not now buy their chickens from an i.s. chicken seller. F*&*ing crap, and a perfect example of how regulating things that MIGHT AFFECT ISC, instead of regulating interstate commerce itself, is, in fact, a licesne to REGULATE EVERYTHING IN THE WORLD. The US Cons gives the Cong. the power to regulate ISC, the US Cons DOES NOT!!!!!!!!!!!!!!!!!!! DOES NOT!!!!!!!!!!!!!!! give the cong. the right to regulate everything that MIGHT AFFECT ISC. If I am a doctor prescribing pot to my patients, or a dope dealer selling my homegrown weed to all my friends and and relatives, then the fed has NO BUSINESS sticking their filthy noses into it.
