 Why does the author think Tom Grey is fighting a losing battle?
It is tough slogging, but for the first time I sense that this commission--though divided, underfunded, timid, and without any power beyond exhortation--isn't entirely useless. This effort has largely succeeded, because Vegas is still the dominant image of American gambling, if not the dominant reality. Instead it will opt for small, targeted policies, concentrating on compulsive gambling. It medicalizes the problem of compulsive gambling, blaming it on psychological abnormality rather than industry machination. Likewise, cracking down on compulsives is also politically cost-effective. In exchange for losing a few compulsive gamblers, the casinos will (falsely) appear more concerned with the health of their customers than with profits. But it can't, because the gambling industry has become so powerful that it's politically untouchable.
 Rev. Grey is trying to warn against the dangers of gambling, but the atmosphere of Vegas makes people feel like they can win and be successful.
 Rev. Grey and his organization do not have the financial backing to fight a political battle with the casinos.  Rev. Grey is trying to warn against the dangers of gambling, but the atmosphere of Vegas makes people feel like they can win and be successful.  Rev. Grey is trying to warn against the dangers of gambling, but his efforts are drowned out by the powerful lobbyists.  People go to Las Vegas specifically to gamble and maybe engage in questionable behavior. They want the thrills Vegas provides. People don't go to be lectured about sinners and morals.
