I can't think of anything meaningful to add to Niall Ferguson's superb argument with which I wholeheartedly concur. From the conclusion of his article, "Obama's Gotta Go":
"The voters now face a stark choice. They can let Barack Obama’s rambling, solipsistic narrative continue until they find themselves living in some American version of Europe, with low growth, high unemployment, even higher debt—and real geopolitical decline.
"Or they can opt for real change: the kind of change that will end four years of economic underperformance, stop the terrifying accumulation of debt, and reestablish a secure fiscal foundation for American national security.
"I’ve said it before: it’s a choice between les États Unis and the Republic of the Battle Hymn."
