I listened to most of Senator Clinton's speech last night.  She is, of course, an extraordinary Democrat.  But her position seems to be:

1.  All the primaries have been conducted;

2.  I'm a bit short in the delegate count but since I'm long in the popular vote count (at least as devotees of New Math may understand her arithmetic), the delegate count is truly immaterial; and

3.  The race for the Democratic Party's nomination ain't over until Hillary Clinton says it's over.

So, take that Barack Obama.

The prelude to Sen. Clinton's speech was an interview I heard earlier in the day on NPR. 

The announcer kept pressing Terry McAuliffe for the time at which Sen. Clinton would begin campaigning for Obama.  McAuliffe's finally conceded that the Democratic Party needed unity from September forward.  He refused to suggest that Clinton would begin to work with Obama before that date.

Let's see how this plays out.
