In other news, Indiana, Texas, Alaska, Nebraska among US states proposing controversial legislation stating "water is wet."
Give me three solid examples of the Federal government "trampling" all over States' rights and powers and I'll lead the secessionists myself. It's called the "necessary and proper clause." Love it.
1) Patriot Act
2) Anything to do with restricting the sale of firearms
3) Anything to do with prosecuting crimes committed in states (criminal law enacted by the national government only applies to the military and being outside of the USA proper, such as on a US ship)
4) Plenty of unreasonable search & seizure, including "information" bureaus trespassing to acquire evidence.
5) Agricultural Adjustment Act
6) Anything to do with the Death Penalty
7) Anything to do with assisted suicide
8) Anything to do with gay marriage
9) Anything to do with marijuana
10) Treaties that legislate law internationally
Even if you see the law as being good, the law itself is illegal. Basically then we can continue on and include a number of issues from pasts wars including the Japanese internment under an executive order during World War II, prohibition and later establishment of a minimum drinking age (setting 21 as the minimum age if a state wanted transportation funds, without which many states would be forced into bankruptcy). On and on.
