John Ellis makes a strong case that Sarah Palin is a real threat to win the Republican nomination for POTUS in 2012. He also sees Romney as her chief rival, but doesn’t think Romney can find enough support among Republicans primary voters to defeat Palin. I disagree with him there. I think either one of them can ultimately win depending on how well they manage their respective campaigns. I would also argue that the field in the Republican Party is still wide open and one or more additional strong contenders may emerge to seriously challenge Palin and Romney.
