One of the more ludicrous comparisons I've seen is Sarah Palin's speech to Sen. Obama's speech at the 2004 convention. Could there be two more different speeches? In 2004, Sen. Obama made a rousing appeal for the country to once again be united in common purpose. In 2008, Sarah Palin made a bloodcurdling scream for our country to retreat behind the barricades in civil war.
Apples and oranges, kids.
