Sorry, but the numbers tell me that third party candidates will take votes away from the underdog, thus assuring an Obama win. Afterall, if they are third party voters, they won’t vote for Obama anyway – but voting for an obscure third party candidate gives Obama the win and throws away your vote. Obama is not vulnerable ENOUGH.
He has the women and he has the unions. He does not have conservatives (where the GOP money is) and he does not have the independants. If they split the vote among third party candidates, we have 4 more years and who knows what will happen with 4 more years of this.
As I said, these third parties can only work in a parliamentary system.
