The level of interest in this U.S. election, is considerably lower than that of 2008. One reason for this may be that any global citizen tuning in to the campaign’s foreign policy debate would have struggled to find substantial differences between what Governor Mitt Romney advocated and what the White House is doing. There is also a growing sense of the relative decline of U.S. global power. The U.S. remains the world’s most militarily powerful country and its largest economy, but its ability to shape economic and geopolitical events in distant climes has steadily declined over the past decade — whether it’s Afghanistan or Iraq, the rapidly changing Arab world or Europe’s debt crisis, Washington struggles to impose its will. That said, the Oval Office remains the world’s strongest single center of power, and the outcome of Tuesday’s vote will be closely watched.
