What is the significance of "returning the power to the states"? 

You hear this a million times in every debate. A candidate is asked about his position on a topic, and ultimately the answer boils down to, "I don't believe the federal government should be making those decisions. I think those choices should be left up to the state." Well, why? Why is it OK if a single state passes x law, but unacceptable if made federal policy? Why should what is "right" not apply to the entire country?

It allows each state to pass legislation that is more tailor-fit to their population. Federal government passes a law that gay marriage is illegal, EVERYONE has to abide by it. Whereas places like Utah that may not be a big issue to the majority of people, places like California where the gay population is larger would be more upset. Similiarly, If the federal government required all personal automobiles meet a 30mpg fuel efficiency. That would go over well in New York, but smaller rural areas like Alabama where people drive trucks for functional purposes alot would be negatively effected. 

Basically, Federal government should be making as few decisions and laws as humanely possible, and leave the states to do their own thing. The only time they should be stepping in is when one state is functionally denying its citizens their constitutionally guaranteed rights. (for example, overruling Chicago Illinois' restriction on people owning firearms, which is protected by the 2nd amendment)
