Figure the house/casino edge is about 10%, and then the government only receives a portion of that 10%. All things considered, the tax revenue from sports gambling is chump change.

But in general, yes --- as sports gambling is legalized, it's probably "stealing" some revenue from the State lotteries.

So that's one reason why Virginia will be slow to legalize. On top of Virginia being a very conservative, professional, and family-values state. Figure Virginia will be 48th or 49th to legalize, and then Utah as 50th.
