Sanders needed to win 20 of the 35 delegates available in Nevada’s caucuses to be on a pace to catch up with Clinton and win the Democratic nomination. He did not get 20. He got 15. Clinton got 20. There was some talk from the Sanders camp about how much closer Nevada was than it looked like it would be a few weeks ago. That is true. But in the end, the result is Clinton getting 57% of the delegates while Sanders gets 42%.

So Sanders falls further behind. Lets look at the charts.

First the straight up delegate counts. We are now at Clinton 487, Sanders 67, O’Malley 2.

In addition to the delegates from the Nevada caucuses, since my last update on the 14th when 42 superdelegates were added for Clinton there have been other updates contributing to those numbers. That includes a number of new delegates identified as being for a candidate, a couple delegates who had been identified as being for a candidate saying explicitly that they considered themselves to be neutral, a few double counting errors corrected, and even one superdelegate dying. The net result was 6 more delegates for Clinton and 2 more for Sanders. And I gave O’Malley back 2 superdelegates who despite his dropping out have not yet stated another preference. In general these changes are backdated to the date there is evidence for them, rather than being dated as of the time I find the change.

Add those all up, and since New Hampshire, Clinton’s total has increased by 68 delegates while Sanders gained 17. If you don’t count the delegates that changed before New Hampshire that I found out about after New Hampshire, it is still 30 Clinton delegates to 17 for Sanders.

Either way, Clinton continues to accumulate delegates faster than Sanders does. That is not a recipe for Sanders catching up. To catch up, Sanders needs to either be getting supermajorities of the delegates from primaries, caucuses and currently unpledged superdelegates, or he needs to be getting quite a few current Clinton superdelegates to defect. So far neither of those things have been happening.

(Note: AP and CNN have Clinton’s delegate totals even higher, presumably due to some non-public superdelegate commitments they know about but haven’t published. The above counts are mostly using superdelegate counts from Wikipedia except for a handful of cases where I have deviated for specific reasons where I believe I have a better count.)

So, how is the “% of remaining delegates needed to win” looking?

Since Sanders has not been making his percentages, and Clinton has, Clinton’s line is slowly dropping, and Sanders’ is slowly rising. Slowly is the watchword here though. Sanders is now up to 55.03%. Right before Iowa, this was at 54.22%. (Counting the postdated delegates, 54.72%.) Sanders hasn’t done well enough that he is actually catching up with Clinton, but he has done well enough to keep the movement on this number low. He is ALMOST keeping Clinton from making progress. Almost but not quite.

As more delegates get racked up, assuming Sanders continues to collect less than 55% of the delegates, it will not only get harder and harder to catch up to Clinton, it will also get harder and harder to prevent that red line from zooming downward to zero, the point where Clinton wraps up the nomination.

For now though, while he isn’t stopping her, Sanders is clearly slowing Clinton down more than she would like.

Next up, South Carolina.

Update 2016-02-26 15:55 UTC – Completed a scan for superdelegate changes. Net result is +6 Clinton superdelegates… plus one new O’Malley superdelegate. This is not actually a NEW O’Malley superdelegate, but one that declared their support back in November but just hadn’t been logged yet, and there is not yet evidence of them stating they are now uncommitted or backing another candidate. These changes have no substantive effect on the analysis above.

Update 2016-02-28 03:24 UTC – Another scan for superdelegates in preparation for adding in South Carolina results. Net result Clinton +4, Sanders +1. This again has not substantive effect on the analysis above, but putting a note here since it is not worth a blog post of its own.
