It is only a throw away when a bunch of other people don't vote that way. If we have enough people that want someone other than those two we shall have it.
Well, exactly. And no one wants to be the first group of voters tha break away from the pack.
Let's say you have Party A and Party B. Party C comes along with some really great ideas.
Due to the 2-party dichotomy, people in Party A hate Party B and vice versa. Now if you are going to throw your lot in with Party C, you need to know that they will win. If they don't, your vote is lost from Party A and thus gives Party B an advantage. So until there are clear indications that Party C will win, you don't change your vote. And since the 2-party system is deisgned to deny a 3rd party a chance, it's unlkely that you will ever be convinced to change your vote.
You can bet if those two parties piss people off enough THEY WILL vote for someone else. There just hasn't been anyone people agree with and like enough to change the status quo. That can always change. Ron Paul came pretty damn close to doing it. Ben Carson is another outsider that has managed to sway a lot of people. Rand Paul has quite a following across the party lines. I think the right person with a socially liberal and fiscally conservative agenda could manage it but it would take a lot of people realizing that their stock party favorite is just talking the talk and will once elected walk the same walk they all have.
Ron Paul made some noise. But when it came to the actual election, not the news cycle leading up to it, he was a non-factor. Again, because the majority of people won't jump on board until a 3rd party is a favorite. And a 3rd party can't become a favorite until a majority of people jump on board.
Instead what we see is Party A blaming Party B and Party B blaming Party A. We see a new party in the White House every 4 or 8 years, and we see entrenched incumbents and tight races making people feel like there is some kind of choice.
We have both kind of music, Country and Western.
We have a choice of beverages, would you like Diet Coke or Regular Coke?
