Karen Travers of ABC News’ Political Unit crunched some numbers on my request.
Since March 14, when the Rev. Jeremiah Wright story first hit GMA, Sen. Barack Obama, D-Illinois, has picked up 62 superdelegates to Sen. Hillary Clinton’s net of 20.
Since April 22, when Clinton handily won the Pennsylvania primary, she has netted 12 superdelegates to Obama’s 21.
But since Wright appeared at the National Press Club on April 28, she has netted 11 — and he has gained 17.
UPDATE: Inevitably, moments after posting this, the Obama campaign announced two more superdelegates — so just today he has gained three to Clinton’s zero. But the day is still young.
