The Washington Post, a conservative leaning paper, has
endorsed Obama today. Their explanation was a bit scathing towards McCain's campaign at times:
The choice is made easy in part by Mr. McCain's disappointing campaign, above all his irresponsible selection of a running mate who is not ready to be president.
But it's also clearly praising Obama:
It is made easy in larger part, though, because of our admiration for Mr. Obama and the impressive qualities he has shown during this long race. Yes, we have reservations and concerns, almost inevitably, given Mr. Obama's relatively brief experience in national politics. But we also have enormous hopes.
...Mr. Obama's temperament is unlike anything we've seen on the national stage in many years. He is deliberate but not indecisive; eloquent but a master of substance and detail; preternaturally confident but eager to hear opposing points of view. He has inspired millions of voters of diverse ages and races, no small thing in our often divided and cynical country. We think he is the right man for a perilous moment.
