ADK voting no doesn't necessarily indicate that he's liberal, since he was in line to become president that round anyway. However the yes and no votes to M1 become interesting, I think that does make it more likely that ADK is liberal. Hmm... just based on votes so far I would say:
gkrieg13 - Voting pattern looks ehh, however both fascists I know voted the mission down, so... slightly liberal.
A Drowned Kernel - on ghosts proposal one, which many fascists voted down. Voted down R2.1, but was in line for presidency. Slightly liberal.
ghostofmars - Was picked by a fascist for a mission proposal, which I think makes him unlikely to be a fascist himself. Liberal.
Hydrad - Voted up M1.1, but also voted up both fascist missions. Sightly fascist.
Grujah - Voted down M1.2 and voted up M1.1. Liberal.
faust - Uh, so faust actually voted down M1.1 and then voted up both other missions, which were both fascist. That's... interesting. I know he's given reasons for these votes before, but just based on the votes, fascist.
When I add in reads based on posts and whatnot, faust drops down a fair bit, and that I feel leaves Hydrad as my top scumread? I don't feel like his posts have convinced me of anything yet. Faust could still be scum, mind, so probably one of those two would be my best investigation target.
