A few more thoughts on Halperin's dissent from reality:
Whatever Barack Obama says or doesn't say on Tuesday, there's one thing that even Mark Halperin won't be able to dispute: as of Tuesday, Barack will have won the primaries and caucuses, fair and square. And once that has happened, there's no way the superdelegates are going to turn things back.
If it's not over now, it will be then.
