One of the problems for honest Clinton supporters is that the comments a real Republican Troll would leave do not have to be far different than what Senator Clinton herself called for in the Friday conference call to her bloggers.

The only clear differentiation is that Senator Clinton is calling for all of her supporters to support the Democrat nominee.  You cannot expect that to come from a Rep. Troll.  

On the other hand, it is my belief that many Clinton Bloggers who are pledging support to John McCain are not Rep. Trolls either, but actually mean what they say.  So there is imho no real way to clearly ID a Republican Troll in these cases.

As an Obama supporter, on the other (third?) hand, I have no great hesitation to call out a supposed Obama supporter behaving similarly as a Rep. Troll.  There has never been a call from the candidate or the campaign encouraging the types of intentional devisive tactics as Sen. Clinton calls for.  Quite the opposite.  

Any Obama "supporter" using such language is more likely - again imho - to be an opposition Troll than a real supporter.
