Which presumptive nominee for President would best handle the wars America is fighting?
This question will inspire even more intense debate after Barack Obama's trip to the war zones in the coming days.
Tonight, Andrea Mitchell, already in Baghdad tonight, reports on the timing and risks and reasons for his trip, and she will include rare interviews from the very men who will debrief Obama: General David Patreaus and U.S. Ambassador to Iraq Ryan Crocker.
(Forgive me for this digression, but honestly, whenever I write Andrea Mitchell's name, I actually pause because my brain wants to write Andrea the Great, as in truth, she is.)
As you might expect, John McCain has some things to say about Obama's trip and some of those things are perhaps surprising, as we will hear from Kelly O'Donnell, on the set with us tonight.
There is also real war news today. President Bush and Iraqi Prime Minister Nuri al-Maliki have come to a hard-fought agreement on a "time horizon," but not a "timeline," for reducing the number of U.S. troops in Iraq. We will have details on what this means.
Also tonight, stories with stunning pictures, including an especially cool one showing us a rare glimpse of the dark side of the moon. Bet it tickles your brain this Friday evening.
