Brazil’s casino legalization efforts may hinge on the support of evangelical Christian legislators, who don’t appear wild about authorizing new sins for their flock.

Brazil’s President Jair Bolsonaro recently met with members of the ‘Central’ bloc of the federal Chamber of Deputies, who urged him to press forward with a proposal to authorize casino gambling. Bolsonaro has previously stated that he is personally opposed to gambling expansion but also believes that the issue should ultimately be left up to individual Brazilian states to decide whether they want casinos in their backyard.

However, while Bolsonaro told the Central deputies that he was open to ‘talking’ about casino authorization, he appeared to give the chamber’s significant evangelical bloc a veto over whether the idea advances beyond the talking stage.

One of the members of that bloc is Marcelo Crivella, mayor of Rio de Janeiro and an evangelical bishop. Rio is one of the most desired locations for international casino operators and Crivella has signaled his support for okaying a casino within his city, with the proviso that its gaming floor would be accessible only by international tourists.
