No he can do whatever he wants with Executive Orders.
Google "Executive Order" and see a list of some of the stuff Bush can do. Thanks to his dad, Clinton, and those who came before them.
The fact that any president has that kind of power is scarry. The fact that Bush has it is downright frightening.
Also Google "War and Emergency Powers Act of 1933". It has never been repealed and hence gives the President the power to suspend the Bill of Rights and the Constitution if he so wishes.
Some of the executive orders allows a President to suspend Congress for at least 60 days, which in turn also suspends the Constitution and the Bill of Rights.
By law a State of Emergency needs to be declared to allow the use of these executive orders. Thats simple since the War and Emergency Powers Act was not repealed so it can be declared at anytime. Technically the US has been under a State Emergency since 1933 so the President doesn't even need to declare it but for political reasons he usually does. Many Presidents have done so since 1933 including Vietnam and the Korean War.
Once a State of Emergency is declared FEMA takes control on the ground, if so needed. FEMA is, on the surface, an agency designed by the military to assist in disasters or other states of emergency. Some of the executive orders allow FEMA to take control, on behalf of the President, of people and organize labour camps or move people into concentration camps if security reasons warrant such a move.
If you doubt FEMA then you forget about Florida. FEMA was called in and it had the power to force people to stay indoor and they declared martial law for a time as well during the hurricane disaster.
Just Google it and learn for yourself. Don't take my word for it.
Doesn't all this make you feel good about the US?
