It boils down to consent. I'll not consent to the programs of Romney just because he grades a D- to obrahmas F according to GOA. That degree of separation is similar to the "differences" between the two on many other things as well. There are only two forms of government, government by force, and government by reason. I'll not consent anymore to government by force. In this particular election, voting doesn't make a difference, as there aren't two opposing views as to how things should work. Both are thieves, they just have a different circle of friends who will benefit from the loot.
