While I will vote for Obama again and believe that he is a leader of integrity and intelligence, I gasp at the level of US debt ($18 trillion!) incurred under his administration. Admittedly, he inherited a diabolical financial mess for which we have only George W. Bush to thank, but I believe Obama lacked both the political and business experience that would have enabled him to do better. I have to believe that he has learned lessons and - with nothing to lose in a second term - will make the hard decisons the US economy requires.
Romney may be the better businessman, but his record as a flip-flopper means no one can trust what he says. Because he has been perceived as "too liberal" (not to mention "too weird") for his Republican base, he's reversed his views on abortion, healthcare, climate change, tax cuts, gun control, etc. We've recently witnessed his stupidity abroad. Nothing about the man is reassuring.
The sad fact is that the election will be decided on the economy, which does not work in Obama's favour, at least not at the moment. And the Republicans will swallow their reservations about Mitt and vote for him because he is NOT Obama. It's going to be close!
