I think you're accepting a lot of "false flag" attacks from the Right as coming from real Obama supporters, RY62, just as I think there's a lot of "false flag" support for Clinton, as well. Rather than building up their own candidate, repubs are trying to tear down the other side, fracture it, any way they can.
Pliablemoose's comments seem typical in that regard, attacking the Clintons. I'd assess his chances of voting for anybody other than McCain as zero. The notion that the Clinton's don't play fair has no reference point, so perhaps we should establish a few- Maybe the Willie Horton Show, The Ken Starr Show, The McCain's Black Baby Show, the Swiftliars' Show, or the Democrats as Terrarist! Sympathizers show... those aren't the only examples of repub sleaze, either, but they'll have to do at the moment... The Clinton's couldn't match that record if their lives depended on it...
