Well, Sara--the questions about each ammendement of the US constitution, relationship between each branches of the government with the States are not that simple -:)))) It warrants a whole book !
Anyway, I think it's wrong to blame everything that went wrong in Katrina disaster on pres. Bush. I believe that responsibility should be shared between federal, state and local officials. Country needs to re-learn how to be prepared and respond to catastrophic events efficiently.
thank you Sergiej how are you good friend?
