Personally I think that anyone who says it will make no difference regarding the future of RKBA whether Mcain or Obama is elected, has their head in the sand.
I don't mean that as a flame. Just look at the Supreme Court. The next president will likely appoint at least one member. Do you honestly think that Obama is likely to appoint a justice who will respect the Second Ammendment?
Also, If Obama is elected, the Democrats pick up enough more seats in the house, and there is a mass shooting of some kind that the Media is able to whip into a frenzy, we will be looking at AWB2. It is absolutely foolish to think otherwise. Look at the history of these people. Don't buy the lie.
