DOVER, Del. (AP) — An industry group representing Delaware's three casinos is asking state lawmakers to revise revenue-sharing models so that the casinos can remain profitable amid increasingly intense competition from casinos in other states. Casino representatives on the council also voted Thursday to ask that the tax rate on table games be revised, either by lowering the rate or by subtracting half the revenue to help casinos cover payrolls for the labor-intensive games before distributing the remaining money among the state, the casinos and the horse racing industry. Representatives of the horse racing industry are opposed to increasing the state share of slot vendor fees or earmarking half of table game revenues for casino payrolls because those moves would mean less money for the horsemen.
