What is it with actors? They play a role then magically assume they’re experts in the field of their character.
Not only that, but their profession always allows a do-over. Kevin Spacey can be shooting a scene for a movie, flub his lines 57 times in a row, and will still be given that 58th opportunity to get it right. That is not how the real world operates. Most people don't get to operate like movie actors or US Senators where they get a do-over if they happened to vote the wrong way on something. That's why people like Spacey and Obama are ill-suited for the challenges of leadership. They don't possess the experience of being held accountable for their actions.
