Yesterday, Obama secured the support of 4 superdelegates (Reps. Henry Wexler, Jim McDermott and Howard Berman and Larry Cohen (CWA DNC)), 1 pledged delegate in North Carolina (because of updated vote tallies in the state) and 7 pledged delegates that had previously supported John Edwards. That means that the number for Obama to secure a majority of pledged delegates has gone down from 25 to 17. And the number Obama needs to secure the nomination is 121.5.
The Math
Total Pledged Delegates: 3,253
Pledged Delegates needed for a majority of pledged delegates: 1,627
Total delegates needed for nomination: 2,025
Edwards Pledged Delegates who are now Obama Delegates:7
Obama Pledged Delegates: 1,603
Obama Super Delegates: 293.5
Obama Total Delegates: 1,903.5
Delegates Obama needs for a majority of pledged delegates: 17
Obama need to secure the Democratic nomination: 121.5
