Sarah Palin takes on John McCain, not once but twice. Anyway, McCain wanted "someone to take on the Washington establishment", and she's starting with him!!! What irony??
1) Palin supports a constitutional amendment banning gay marriages, while McCain wants to allow each state to make its own laws in that regard.
