When Reddit did this, the site crashed and the 10,000+ comment thread in AskReddit was full of people "bravely" disclosing racism, sexism, and other rather horrifying "controversial" opinions that amounted to confirmation that Reddit is essentially a wildlife sanctuary for young, relatively wealthy white males to openly wallow in their privilege and be praised for doing so.
I wonder what would happen if Hubskiers--yes, including you, Theory of Reddit migrants--answered the same question?
As a word of warning: if you truly mean this post as an experiment to compare the response on Hubski to the response on Reddit, then the open disdain phrased in your question creates a distinct bias against responding with a controversial opinion that could seen as belonging to a "young, relatively wealthy white male."
That being said, I don't think Romney would have made a bad president. The way he ran his campaign was dubious and I tend to lean Democratic, but even still I still think Romney was a stronger choice than Obama.
