Also, Katniss voting to have a last Hunger Games was disgusting and made me want to throw the book across the room.
I think she did that, not because she actually wanted a last Hunger Games, but to provide public context for her shooting of Coin. The vote was secret. Nobody knew that she voted for it. So when she shot Coin, the natural assumption would be that she opposed the decision and decided to kill Coin in protest.
At least, that's the only sense I can make of the unspoken communication going on between Kat and Haymitch during the vote ("let's see how well Haymitch understands me" and all that).
