First of all, let me actually chime in with Snapple; I didn't think our slightly heated discussion was too bad. I hope this "new" kind of P/R doesn't mean we no longer can be passionate about our views; I always thought that aspect was/is the lifeblood of it.
To the topic, through all my explanations the single basic thing I'm trying to get across is that IMHO the character and personality of a president is an important factor too, alongside with his/her policy ideas, credentials etc. etc.
Look at it this way: A president's job isn't just sitting in the White House and signing bills. He is also a travelling salesman for the United States, pitching for the interests of the country. And you can ask any salesman in the world, they will all tell you that personality is a key ingredient in selling something. If you come across as an ass or an idiot, it will be a LOT harder to get other people, domestic and international, to do what you would like them to do. Look at GWB: Outside the UK, he was utterly unable to garner support for the war in Iraq. Was lacking evidence for WMDs the main factor? Absolutely. Did the fact that the world didn't like him and thought he is rather dumb play a factor? Absolutely too.
That is my point. Romney puts me on guard because I distrust smarmy CEO-like people. That, I think, is not a god sign, because I will not be the only person who has that reaction to him.
