Bill Kristol on Fox News, giving Mitt Romney some good advice for tonight.
"Mitt Romney should, above all, be presidential. Don't try to score every debating point.... don't think of it as a debate.
Think of it as 'This is your moment to be the next president of the United States in the eyes of 60 or 70 million viewers'.
Don't be the challenger to the president, don't be the prosecutor of the president, don't be the critic of the current president, be the next president.... lay out your vision for the world."
Two things.
1. Romney is now the front-runner, and front-runners don't have to interrupt or exploit every opportunity or opening in a debate.
2. In a foreign policy debate, the president has the huge advantage having served (for four years) as "the voice of the United States." That means that voters might instinctively recoil when that voice of foreign policy is criticized. Thus, Romney needs to be careful about appearing too hostile about America's direction on foreign policy. Critical, yes, but hostile, no.
