Pelosi To Superdelegates: Endorse By Next Week!

"After Tuesday, we will [have a clear idea]. I think Saturday will be important, put the Michigan-Florida issue behind us," Obama said Wednesday on a flight from Denver, Colorado, to Chicago, Illinois.

The party's Rules and Bylaws Committee meets this weekend to consider what to do about delegations from Florida and Michigan, which broke ranks to hold primaries earlier than party rules allowed.

"We've got three contests in succession. And at that point, all the information will be in," Obama said, referring to Sunday's vote in Puerto Rico and Tuesday's primaries in Montana and South Dakota.

"I suspect that you know whatever remaining superdelegates will make their decisions pretty quickly after that."
