Atlantic City, New Jersey (AP) -- Financing for two proposed mega-casinos worth [[USD]] 7 billion appears solid, and a third should still get built even if it is delayed by the slowing economy, Gov. Jon S. Corzine said Wednesday. In an interview with The Associated Press, Corzine also endorsed totally smoke-free casinos, and said he would sign a law to keep gambling halls open if state government shuts down, so long as constitutional problems with doing that are addressed.
