Bill Kristol wants to know:

Will any Republican whose career lies mostly ahead of him -- or her -- step up to confront Obama on the foreign policy and national security front? Is any of them enough of a risk-taker to defy the conventional wisdom that if you’re a mere senator or congressman or governor or aspirer to office, you should focus on domestic issues, that it’s hard (and it is) to take on a president on foreign policy? Will any of them seek to join Cheney and Gingrich in the foreign policy fray?

I think we've gotten a little taste so far, with more to come, of Gov. Romney doing just that.
