It seems that there are liberals out there who aren't quite sure what to make of Barack Obama's Nobel laureate status. Apparently, in the word of Matt Yglesias, being given the Prize at this point is "dubious".
Dubious or not, the Prize is awarded for specific efforts - after all, Henry Kissinger has one, too, and he is for all intents and purposes, a war criminal. That doesn't make the prize itself illegitimate. I see no reason in the world why the political dimension - a nod of approval from a certain section of the international community toward the United States and its President - shouldn't be considered an issue of merit and worth.
I should add that Yglesias is also right in that the right-wing howls over the Nobel Committee's decision make supporting the whole thing that much easier.
