Thats complete Bull shit.
Sorry Full usually agree with you, but no it's not. It might suck that voting 3rd party often simply pulls votes away from one guy and not Both in the Election, But it is true. Paul does pull some Democrat Support but not much. So if by your standard the 15% or so who seem to consistently Support Paul Decide to Stay home if Newt or Romney win. Then they are by there non Participation allowing Obama to win. Or at least making it easier for him to.
Hell man the Guy I want is not even Running, I don't like any of em totally. I like some of what all of them say, but I know what I don't like. Obama's Policies, Obama's Class Warfare Rhetoric, Obama's Hyper Partisan Arrogant governing Style. I Can only Imagine how much further left he will move things in a second Term with no election to worry about.
I will vote for any of them who win, Including Paul. Despite the Fact I think his Foreign Policy is Childishly Short sighted and Idealistic. To get Obama and the Left wing Fringe Democrats out of Power. we just have to keep the Pressure on who ever does win, To do the things we want. To stay true to their Election Promises. Because we damn sure know what Obama wants to do isn't what we think is best.
