Left-wing populist candidate Marcelo Freixo made it past the first round in the race for mayor of Rio de Janeiro on Oct. 2, and now goes on to face an ultra-conservative rival in a run-off at the end of the month. In recent days, drug legalization has emerged as a key issue in the race. Freixo, of the Socialism and Freedom Party (POSL), is currently chair of the Human Rights Defense Commission of Rio de Janiero state's Legislative Assembly. He is now running against evangelical senator Marcelo Crivella of the Brazilian Republican Party (PRB) for the mayoralty. But another right-wing contender bounced out in the first round, Flávio Bolsonaro of the Social Christian Party (PSC), has thrown his support to Crivella—and is attempting to use the drug stigma against Freixo, exploiting his call for legalization as a means to de-escalate Rio's violent gang wars.
