Hm, a few Obama fans here...
I don't know if Mr. Romney is a good candidate, and I also don't bother what he's talking all the day long - I'm no American.
However, in a democracy it's very important that an incapable government isn't rewarded with reelection. In fact, that's virtually the only benefit of a democracy at all. So THE question should be - was Mr. Obama a capable president?
Looking at the economical and financial figures I'd say: No. The only strategy that they had and have, was: cheap money and more cheap money.
