1. I apologize for misstating them. But prohibitions and limits are different things, are they not?
2. You seem to know more than myself, so I guessed you might have other examples.
3. Factually incorrect. The recent PPACA case in the supreme court actually establishes that there ARE limits on Commerce Clause power, and the Necessary and Proper Clause do NOT, in FACT, give virtually unlimited power. Section 5000A of the PPACA only survived being struck down due to the fact that it could be interpreted as a tax. IMHO, THAT was wrongly decided, as a Direct Tax is ALSO unconstitutional. Medicaid expansion was also deemed unconstitutional due to it's coercive status.
Bad collective legal interpretation does not a constitutional text or design make.
RE: Trampled rights.
It is not explicit, but implicit, that there should be a balance in some fashion. Electoral College serves that function.
