Some here may be using the delegate counter at
http://demrace.com/ (nice tool).
It seems they've made a small adjustment to the highly contested Arizona results since last Tuesday... Bernie apparently got a few more delegates than first reported there (though the counts in those 3 states are not yet certified). So as the Caucuses began this morning Hillary's pledged delegate lead had dropped to 294.
Now with Washington and Alaska both projected as wins for Bernie with BIG margins of @70% or more, and Hawaii Caucus numbers expected to be similar, the gap could further narrow by another 70 to 100 delegates.
One very Super Saturday for Bernie Sanders.
