Total spending by tribes to keep another tribe from benefitting from gaming was $18 million. Pechanga, which cut per capita from all time highs, spent $2.3 million.
The LATIMES has the story
Rival Native American casino interests spent $18 million last year to defeat Proposition 48, which would have given permission for two other tribes to build a new casino near Madera, just north of Fresno, according to records filed by the campaigns. Another group, including the Pechanga Band of Luiseno Indians, formed a second committee that spent $2.3 million to oppose the ballot measure.
Now that tribes have enriched themselves, they don't want other tribes to benefit. Simply don't want to lose market share, help to Natives be damned.
Pechanga has stolen nearly $600 million in per capita from over 220 tribal members they exterminated and dismembered from their tribe.
