ABC News’ calculations put Obama over the top. Other news agencies differ with those numbers:
With these endorsements, Obama has the support of 267 superdelegates and Clinton has 265 superdelegates.
Every news organization’s superdelegate count is a little different because it is an imperfect science. Since October 2007, the Political Unit has continuously reached out to the nearly 800 superdelegates to determine their candidate preference. We also reach out regularly to the Obama and Clinton campaigns for their superdelegate lists and work to confirm any that they include on their lists.
