At a point like this, you could make the case in every direction.
Britney and Ragan have played the social game, Britney has stepped up and won multiple challenges, and Ragan won POV tonight when his back was against the wall.
The brigade has to be given credit for making it this far with apparent weak game-play in the challenges. No one can raise an objection to their gameplay on the social side. They have written the book on how to make an alliance work and how to ride that alliance to dominance in the game.
If I had to vote right now, I think Britney gets my vote. She has shown the biggest combination of social game and competitiveness in challenges. However, I'll be interested to see if she can make it another week if a member of the brigade wins HoH. They have to be wising up to the fact that she could very well have some votes in the jury house.
However, this is not about my vote for who I would want to win. It's who I think will win. Hayden gets my vote for being the strongest of the brigade.
