Guess there’s no reason to track them this cycle:

At the Democratic National Committee meeting in Minneapolis, where Clinton spoke on Friday, senior Clinton campaign officials are claiming that she has already secured one-fifth of the pledges needed to win the Democratic presidential nomination. They come from current and former elected officials, committee officeholders, and other party dignitaries.

The campaign says that Clinton currently has about 130 superdelegates publicly backing her, but a person familiar with recent conversations in Minneapolis said that officials are telling supporters and the undecided in the last few days that private commitments increase that number to more than 440—about 20 percent of the number of delegates she would need to secure the nomination.

Final numbers are still in flux, but current estimates peg the total number of delegates to next summer’s presidential nominating convention at about 4,491, meaning that a candidate would need 2,246 to win. The Clinton camp’s claim to more than 440 delegates means she’s already wrapped up the support of more than 60 percent of the approximately 713 superdelegates who, under party rules, are among those who cast votes for the nomination, along with delegates selected by rank-and-file voters in primaries and caucuses beginning next February.
…
To be sure, Clinton had a superdelegate edge early against Barack Obama in 2008, and superdelegates are free to change their allegiance at any time between now and next summer’s convention. But Clinton is ahead of the pace she had eight years ago in securing these commitments, and her support from the core of the establishment represented by these superdelegates is arguably the most tangible evidence of the difficulty Biden would have overtaking her with a late-starting campaign.

This is not 2008. But it’s not about being ahead of the pace. It’s about the fact that Biden has 2 supers (both from DE), O’Malley 1, and Sanders has 0. Clinton continues to have the nomination locked up.
