Uh... did I say I support it. Go re-read my posts because you didn't the first time. Pointing out facts of the matter as they stand is one thing. I also stated I do NOT like the legislative branch abusing this power as they did with the Cannabis ruling for example to get what they wanted. Acknowledging the power and abilities of the legislative branch is a far cry from deeming what all the do as right.
The fact remains that Congress has this power. There is a reason they have this power and many times it has been proven businesses need to be regulated. Otherwise crap like Enron or worse happens. I'm not saying Congress can't foul things up worse, but they need to have the power to regulate when it is needed. There is a difference between recognizing the have the authority and advocating them when they abuse that authority on occasion.
Your assumption is that the state cannot do the job the federal government is currently (trying) to do in terms of regulating commerce within its own borders.
The simple fact of the matter is that the currently congress could enact laws to restrict alcohol (once requiring a constitutional amendment) through a simple law (as they do with Marijuana).
So Congress "has the power" now but didn't before FDR. What change in the physical document of the constitution granting these powers to congress?
(And don't tell me that Congress can do whatever it wants as the 10th Amendment clearly state that powers NOT granted to the federal government are reserved to the states and the people)
