Well, I'd like to point out that the key to this game is twofold for red/blue:
Make the first victory. Do whatever it takes to win the first vote. Manipulate it all, talk to everyone. Scare whomever. Whatever it takes to vote off the opposing team's color.
From there, don't be greedy. Try to work with the other team to eliminate the "mafia" team, in this case, the green team. Make connections, be straightforward. The truth is, if your team captured the number advantage that first day, then as long as you can convince the opposing team to go after the mafia team with you, then you have little to fear. At the end, you'll have greater numbers than the opposing team, and items, truthfully, should neutralize each other in the long run.
The wrench in my plans? The item mix-up made me believe one enemy was a team member with absolute conviction, and secondly, I while I could get the blue to support me in going against the green, I wasn't able to convince my own team to. For some reason, I was perceived as a threat to some red team members, despite not once doing anything threatening towards them. (Seriously, I threatened stevey, Mop_it_up, Maxi, and Khush, and killed Stratos without a threat. What was up with that, red team!?)
