Unless I got my math wrong that's how many delegates Clinton needs to lock the nomination.

Sanders needs 1026 to do the same.

There are 1241 delegates (including unpledged super delegates) remaining.

In 2008 super delegates defected from Clinton to Obama. That is what shifted the balance enough to give the nomination to Obama.

Does Sanders campaign have a plan to woo those delegates away from Clinton?
