I said ILFJ, Joker, and Fr3sh were my top three suspects earlier.
Do you think the G's are sacrificing Joker to gain credibility? If Joker turns out to be a G, which is likely IMO, it gives them much more credibility of they voted for him first. If he says he's autolynching anyways...? If Matt is a C, I don't see how anyone could see Joker as a C. I'm wary of his being sacrificed to better their position.
