New Jersey Gov. Chris Christie says the state could double its gaming revenues with the legalization of online gambling, and many other experts say online gambling will benefit bricks-and-mortar casinos. Gene Johnson, a senior vice president of Spectrum Gaming Group, noted, "It will be much more connected to land-based gaming than we see in Europe. We strongly believe it will drive some incremental business to the physical casino." However, some casino industry veterans are worried that it will not live up to expectations. "It's so new and unproven that it's a flip of a coin," said Ed Spotts, a tourism instructor at Temple University in Philadelphia.
