Taxes on Internet gambling could raise between $8.7 billion and $42.8 billion in a decade, according to an analysis by the accounting firm PricewaterhouseCoopers that McDermott released last month. But Frank Fahrenkopf, president of the American Gaming Association, questioned those numbers.
Fahrenkopf said many states are unlikely to authorize Internet gambling even if the federal ban is repealed.
McDermott spokesman Mike DeCesare said the tax revenue estimate was made so wide in an effort to be credible.
"I still think the odds are very long that a bill (to repeal the Internet gambling ban) will pass in this Congress," Fahrenkopf said.
Fahrenkopf said he is troubled by the prospect of federal regulation and federal taxation of the gaming industry.
"This is a matter for the states, not the federal government," Fahrenkopf said.
McDermott's original bill had only one co-sponsor -- Rep. Neil Abercrombie, D-Hawaii. The bill he offered Tuesday has no co-sponsors.
