Heading into a lunch break, the Obama and Clinton camps are sparring over what is and isn't a concession in their sparring over Florida delegates. 

The Obama camp says it's making a concession when it agrees to allowing Florida half its delegate votes. That would give Clinton a net gain of 19 delegates, up from the zero delegates she gets under the current rules.

"An extraordinary concession," says Rep. Robert Wexler of Florida, an Obama man.

"A concession? Give me a break," counters Clinton man Harold Ickes in the hallway outside the party meeting.

He argues from the standpoint that Clinton has a net gain of 38 delegates in Florida. "Hillary Clinton loses delegates."

But Clinton doesn't have any Florida delegates now, let alone an edge of 38. Florida was stripped of all of its delegates.

Score it for Obama. Clinton can't lose delegates she doesn't have.
