While everyone is focused on Pennsylvania as the next big primary actual delegates are being chosen all of the time.
You have the state conventions meeting and making the actual decision based on caucus support you also have states adding on a total of 81 additional delegates - bigger than most states and roughly half of the lead that Obama has over Clinton.
Here are the details of the "ADD ON DELEGATES"
http://www.demconvention.com/how-to-become-a-delegate/Add-on delegates - May be selected by either the same selecting body that selects the state's PLEO delegates or by the same selecting body which will select the state's "at-large" delegates. They can be selected whether or not they previously filed a statement of candidacy for a delegate position or submitted a pledge of support for a presidential candidate. There are both pledged and unpledged add-on delegates.
A total of 81 delegates (75 if you exclude Florida and Michigan) will be chosen between Feb 23rd and June 21st by individual states- most states get 1-2 delegates. So far 5 delegates have been chosen. One would expect that the small states who only have one delegate and are predominately Obama big win states would be appointing mostly Obama delegates. Bigger states that have 3 or 4(New York) or 5 (California) would likely see split appointments.
Again you would expect that after all of the add-on delegates were appointed that there would be another net gain for Obama of 10-15 delegates.
