"Majority of FR" - I've watched all the anti-Romney threads. Based upon the response to those threads, I think we are talking about 1000 vocal members, maybe 1,500 in a nation where >130M are going to vote. Let's be realistic, every one of the posters on FR that have bashed Romney could stay home and not effect the outcome in a single state.
The problem with practicing "all or nothing" politics is that the vast majority of the time you end up with nothing.
That said, we presently live in a free country, so everyone can do what they wish. I've chosen to vote against Obama. I am certain what kind of politician he is. As to the alternatives, we can only speculate about what kind of President they might be. The only thing for certain we know about the entire lot of them is that they would all lie to win. After all, they are politicians.
The only difference between romnuts and the bamster is skintone.
