Biden is exceeding expectations, but Bernie Sanders is winning decisively in California, so it looks like under the Democratic Party formula, (Proportional apportionment of delegates above a 15% cutoff) Sanders will get more delegates.
Not a great night for Sanders, but not horrible either.
The losers tonight, Warren, who will place third in her home state of Massachusetts and finish completely out of the delegate count in California, and Michael Bloomberg, who appears to have won only the primary in American Samoa. (Tulsi Gabbard actually won her only delegate there)
