I guess this one has to be about Libya...
Part of the liberal fear about Libya seems to be that the administration has not really thought through the downside properly; many liberals, even those who are okay with the concept of aiming American bombs and missiles at bad guys and who agree that Qaddafi is a bad guy, don't believe that anyone has answered the "what comes next?" question to their satisfaction. Here's my question: do you trust Barack Obama to avoid turning this thing into a morass? Any more than you would have trusted, say, George W. Bush? Bill Clinton? Why or why not?
Or, to put it another way, how many coalition deaths do you expect in this intervention? 0-10? 11-50? More than 50? More than 500? Would your expectations be any different if any of the other recent presidents was serving now?
(Of course, there are certainly liberals who would oppose this action on other grounds; if you're in that boat, feel free to answer this one any way you would like).
