You clearly do not know what a concern troll is. A concern troll is not someone posting an opinion, it is someone first lying to conceal their motives, and then posting in a way that is deliberately, purposely, destructive to the candidate the that they claim to actually support. It is a concealed, cowardly form of deliberate attack which is a huge turn off to honest freepers.
" I love x and I am his biggest fan, and can't wait to vote for him in the election, but I am concerned about the claims about him and his college days as a male hooker though-- oh you didn't hear about that?"
"I love x and hope he wins but, etc, etc, etc."
When someone does that in a way that raises your antennae, and then you check his posting history and see that he has been doing that on thread after thread, then you have caught a phony poster that is attacking the subject and trying to camouflage the attack as the concerns of a supporter, it is a way to attack a popular conservative here without drawing heat, unless someone catches on and outs you. It is a cowardly way of lying.
It is a common occurrence. I will be honest and cut to the chase, if anyone expresses that they would like to see the field of 2012 candidates before they support Palin or anyone else, they are a troll or a Mittbot or even from DU. There is nobody around here that is dumb enough to think that the attacks on them are sincere or reasonable. Truth is, most of the people here will end up supporting the candidate from our side that opposes Obama. If that is Palin, so be it, she will have people behind her. If not, I guarantee it, she will support whoever that is also. So what is the damn problem at this point?
