Should Democrats make Bush/Cheney work to win the South ?

[kentuck]

Many political observers are now saying that North Carolina has become a battleground state since Kerry has picked Edwards to be his VP candidate. These same "experts" are saying that Democrats also have a shot at winning Louisiana, Virginia, Arkansas, and Tennessee. Some Democrats in Georgia are now saying that state is in play since Edwards has been added to the ticket. Edwards is very popular with black voters.

If the Democratic polls show the above scenarios to have some validity, should the Democrats campaign in these states to win? And would that not put a lot of pressure on Bush and the Repubs to defend an area which they were taking for granted and which, they cannot afford to lose even one or two states. This is a serious threat to them. Should the Democrats devote more time to these states in the South?
