My current guesses on delegates tonight and percent needed going forward for each candidate
First a caveat: all these numbers are fluid, particularly with people in AZ still voting and, even when we're not right in the middle of a night's voting process, it's hard to determine the exact number of delegates allocated. But based on:
Pledged delegates only (assuming un-pledged can change, as they have in other years)
Numbers from RCP tonight before any primary results came in gave
HC 1119 and BS 813 pledged delegates.
A reasonable guess for tonight's delegates might be Green Papers numbers for AZ, UT, and ID (but note these numbers can and probably will change over the next few days):
..........HC.....BS
AZ......45.....30
UT.......8.....25
ID.......5.....18
----------------
Total...58....73 (so maybe Bernie reduces Hillary's lead by 15 or so)
new totals HC 1119 + 58 = 1175
..............BC 813 + 73 = 886
So the percent-needed, under these assumptions, gives:
Hillary: 1175 pledged, so 2026 - 1175 = 851 to go
Bernie: 886 pledged, so 2026 - 886 = 1140 to go
since there are 4051 - (1175 + 886) = 1990 pledged left to be allocated,
Hillary needs 851/1990 = 42.8% of the remaining pledged delegates
Bernie needs 1140/1990 = 57.3% of the remaining pledged delegates
