Echoing what I wrote last week, Jonathan Alter at Newsweek also thinks Hillary would do herself and the Democratic Party the most good by dropping out now, before March 4:

If Hillary Clinton wanted a graceful exit, she’d drop out now—before the March 4 Texas and Ohio primaries—and endorse Barack Obama. This would be terrible for people like me who have been dreaming of a brokered convention for decades. For selfish reasons, I want the story to stay compelling for as long as possible, which means I’m hoping for a battle into June for every last delegate and a bloody floor fight in late August in Denver. But to withdraw this week would be the best thing imaginable for Hillary’s political career. She won’t, of course, and for reasons that help explain why she’s in so much trouble in the first place.
