Proponents of a Prince George’s County casino are scrambling to rally support for a deal that was nearly killed but then was given new life by Gov. Martin O’Malley.

O’Malley and House Speaker Michael Busch, D-Anne Arundel, are expected to meet in the next few days with Senate President Thomas V. Mike Miller Jr., D-Calvert and Prince George’s, to discuss the possibility of a special session, despite the failure of a commission of senators, delegates and state officials to reach a consensus.
