Not an American, but a few things I know for sure.
Obama is a man with a mission. Granted, not everyone in the United States may agree with his measures (his healthcare bill comes to mind), but at least he has concrete plans in mind. Romney doesn’t seem as focused, and doesn’t seem to have a clear plan of action if he takes office. He regularly flip-flops, changing his views whenever they suit public opinion.
In a news article, they quoted Romney twice – the first quote saying he wanted to fight in the Vietnam War, and another quote where he claimed he had opposed the Vietnam War all along.
Romney claims to bring sweeping changes, yet I saw a video edit of Romney’s speeches spliced together with Obama’s – granted, the source may have had a liberal bias, but in terms of their actual speech, both candidates’ stances on major issues (Iraq, for instance) is remarkably similar, right down to the precise wording they used.
Obama is still more popular overseas. Yes, global opinion may not matter much in a domestic election, but could well factor into the aftermath. As has been cited before, many desire a second term for Obama, fearing the results of Romney’s foreign policy. If Romney were to be elected, I foresee a significant international backlash fueling already rampant anti-US sentiment.
As I type this, the first polls open in half an hour. Another thing I know for sure – whatever the outcome of the election, the world will be a changed place.
(On a side note, watch out for the leadership handover in China. Combined with the US election, Sino-US ties could head in any direction.)
