Britney has no game strategy at all. Her social game is entirely defensive, the object being to keep her ass covered week to week. Instead of taking her nomination as a personal insult, she should see it for what it is: a game move and respond with a game move of her own.
But all we hear are insults about Dan. He didn't use the Veto and he didn't nominate her either. He made a move, but Britney can't respond in kind, because she wouldn't know a playbook if somebody slapped her upside her head with one.
