Like the others really had a chance of winning?
Irrelevant.
As I see it Romney was so close to Obama, politically, that his win would be virtually indistinguishable from an Obama win [policy-wise]. (IE Romney and Obama are only a few cents different when compared to ideologies of, say, JFK or RR which would be [at least] hundreds of dollars different.)
Besides, to say that they didn't have a chance of winning is to say that their votes did not count [because their candidates lost] and yet Romney lost, so then does that make the votes for him not count? -- You cannot have it both ways: either a vote for someone who loses counts or it does not, and if it does not then why vote?
