“Effectively clinching” is not clinching, which requires attaining a prescribed number of pledged delegates. Until the convention the superdelegates are free to change their minds as often as they like.
Exactly right. What I find ironic is that whole concept of the superdelegate is to make sure that the Democrats have the capabality -- right up to the last minute! -- of changing their mind and saving themselves from a candidate who has suddenly become unelectable.
The DNC understands the purpose of the superdelegates.
The media understands the purpose of the superdelegates.
But it suits their purpose (today) to slap their hands together and say "Game Over!"
But they know it's not.
