If Romney is elected there will be no change, he has already said he wants to work with democrats.
That's one of the boneheaded, backward things that sunk McCain. The time for "reaching across the aisle" may be over.
In Senator Jim DeMint’s new book, Now or Never, he says the following:
“The differences between the Democratic and Republican Parties are irreconcilable: there can be no compromise between collectivism and freedom.”
Sure there will be change - mittens will apply a nice coat of whitewash. ;-)
