I'm not sure you're correct about 60 million, if you are, you're correct in both parts. Honest discussion is difficult, at least in the public sphere. I don't encouter that other than occasionally on a personal basis. The public sphere, millions, being the more significant. As to the 12 million fewer voters, I've asked a few times on the thread about the 2.3 million McCain voters absent. Less concerned about the missing Obama voters.
I voted 3rd Party for President; the anointing of Romney by the GOP, from long before the primaries, indicated to me that they were all about talk and not about action. Consider Romney's past: he's really liberal -- how can you get socialism out of the office by electing a socialist?
Obviously the GOP wasn't interested in my vote. Indeed, they weren't interested in any conservative or constitutionalist's vote.
