Should the bill pass in the House, only some provisions could be vetoed by the governor. According to the attorney general's office, provisions that would allow table games and permit a sixth casino site could be vetoed. A provision that would make expansion to Prince George's County contingent on a referendum by county voters takes the form of a constitutional amendment and could not be vetoed.
Overall, O'Malley expressed satisfaction with a "very productive" session during which he has already scored some high-profile victories — notably the passage of a bill legalizing same-sex marriage — and is on the verge of racking up several more. The same-sex marriage bill is expected to be petitioned to a referendum in November, and the governor said he would take an active role in the campaign to win voter approval of the law. But O'Malley said he would carefully pick his shots in making his arguments.
