I don’t think it’s the same people saying both. Would love to have an actual FR poll and having to sign in with user names, although we have a lot of people who read and never sign up.
In the past few months, for every FReeper who stands on the side of "any Republican is better than a Democrat and I'm going to keep on voting that way," there are about 1.8 FReepers who say, "Forget that loser's game." However, most FReepers either don't say one way or the other, or are too ambiguous to tell whether in the voting booth, they're willing to snub both the Republican and the Democrat.
In 2012, folks sure voted the same way I read them on FR, which was about 1.5 "screw Romney and the Donkey he rode in on" to every 1 "Romney's not as bad as Obama -- I'm voting for him." Romney lost. GOOD.
