From NBC's Domenico Montanaro
NBC NEWS has allocated 50 of the 55 delegates in Puerto Rico with a split of 35-15 for Clinton, so far. Five delegates are not yet allocated.
The NBC NEWS Delegate Counts:
PLEDGED: Obama 1727 to 1622
SUPERDELEGATES: Obama 329 to 293
EDWARDS PL. DELEGATES: Obama 16.5 to 0 (adding the 4.5 from Florida)
OVERALL: Obama 2,072.5 to 1,915
* Obama is 45.5 from the magic number of 2,118. (Clinton needs 203.)
* There are 237.5 total delegates remaining -- 36 pledged delegates at stake between today's contest in Puerto Rico (5 remain) and Tuesday's primaries in South Dakota and Montana. Plus, 201.5 undeclared superdelegates remaining.
* That means Obama needs 19% of all remaining delegates. Clinton needs 85%.
