Answer to Question 2
An ideal response would be:
There has been a dramatic increase in legalized gambling in the United States. For many years, only Nevada permitted legalized casino gambling, but in 2010, 15 states permitted commercial casinos, 31 had casinos operated by Native American tribes, and 43 permitted pari-mutuel betting on horse and greyhound races and the game of jai alai (in Florida). Only Hawaii and Utah do not permit some form of legalized gambling, although as of 2012 Hawaii was considering changing its law. The spread of casinos was in part a consequence of Native American tribes asserting their right to self-rule on reservations and establishing casinos in states such as California, Michigan, Connecticut, and South Dakota. In addition, gambling companies asserted that prohibitions against land-based casinos did not apply to floating ones, and they promoted gambling on riverboats and dockside casinos.
State revenues from non-lottery gambling (casinos, pari-mutuel betting, and hybrid
casino-racetrack facilities) grew every year from 1998 through 2008 but then dropped in 2009 and started to grow again in 2010 . In 1998 states collected some 2.9 billion in revenue from non-lottery gambling; by 2010 this had grown to just over 6 billion. Yet states varied greatly in their reliance on this revenue source. In 2009, Nevada received 12.5 percent of its general revenue from gambling while Rhode Island and West Virginia received 8.4 percent, and 19 other states received 2 percent or less of their revenues from these sources.
