We've reached an important landmark in the presidential campaign: President Obama and Gov. Mitt Romney face off tonight in the third and final presidential debate.
As was the case the last two times, the debate starts at 9 p.m. ET. This time, the venue is Lynn University in Boca Raton, Fla.
If you believe the snap polls, the first debate went to Romney, the second went to Obama, which means we have a 1-1 tie with just minutes to go in the fourth quarter. That is to say, we're just two weeks away from Nov. 6.
As we just heard, the candidates have already said a lot about foreign policy, but they have not necessarily addressed every question. Tom Ricks has been thinking about a subject that lurks somewhere beneath almost all discussions about global hotspots. Ricks has covered the U.S. military for the Wall Street Journal, the Washington Post, and in many books. His most recent work, "The Generals," examines top military officers in recent history and their grasp of strategy.
Now is the moment in the program when I admit that I am a total Star Wars nut. Those of you with me, you might recall that Luke Skywalker's home planet of Tatooine enjoyed the warmth of not one but two suns. That dramatic scene, you remember Luke at dusk gazing at the weird peaceful sunset.
