Reasonable people can disagree about the nature of Palin's difficulties. Some will argue that Palin just hasn't had time to learn about government and policy issues. Others will argue she isn't very bright. Others still may make the case that she's just cracking under the pressure. But the cause isn't especially important -- reasonable people should agree that the Republican vice presidential nominee is way out of her depth, and has no business seeking national office.At the risk of sounding impolite, Sarah Palin is embarrassing herself, her party, her ticket, and her supporters. The notion that she could be the leader of the free world sometime fairly soon isn't just ridiculous, it's terrifying.Really, what is it the earnest Republican is thinking watching an interview like this? Does it give him or her pause? Does he or she cringe, but suppress the fear for the good of the party? Does he or she simply buckle in, get into a crash position, and hope the Republican ticket doesn't screw the nation too badly?
