The difference is I think Biden is a smart man who speaks without thinking and just sounds and acts stupid .He is knowledgeable on foreign policy and semi knowledgeable on other issues.Palin is not knowledgeable nor is she smart imo I compare Biden to Bush Jr.I think Bush is a silly idiot like Biden,but is smart and knowledgeable enough to make sound decisions,even if I dont agree with those decisions.
you really need to either move next door to Palin or follow her on tour since you're so obsessed. the rest of us know she wont get the nomination. but if she can serve to be a lightning rod and stir up the public against obama in the meantime, that may be her calling.
