Dan Drezner declares that business savvy doesn't predict presidential effectiveness:
The thing is – and this is kind of important – governments are not corporations. I cannot stress this enough. There's the obvious point that in democracies, legislatures tend to impose a more powerful constraint than shareholders, making it that much harder for leaders to execute the policies they think will be the most efficient. … There's been a lot of bragging in the 2012 primary about candidates that have "real world" business experience, and how that translates into an effective ability to govern. That logic is horses**t. Being president is a fundamentally different job than being a CEO — because countries are not corporations.
