Following the protests that occurred in Brazil in June, Rousseff has fulfilled a promise by requesting Congress to organize a non-binding national vote, or plebiscite, to determine what changes Brazilians desire. She has outlined various topics she hopes will be addressed during the vote, such as campaign finance reform, eliminating anonymous votes by lawmakers, and potentially moving from proportional representation to district voting. Recent polls have shown a significant drop in Rousseff's approval ratings, indicating that the protests have posed a serious threat to her chances of being re-elected next year. Over a million people participated in the protests, expressing discontent with poor public services, high living costs, and the large sum of money being spent on hosting the 2014 World Cup. The demonstrations have made it clear that Brazilians are demanding a more efficient and transparent government, free from corruption. While the protests targeted politicians from all parties, Rousseff's popularity suffered, prompting her to call for a plebiscite to gather the opinions of the people. She stated that the protests represent a desire for increased rights and representation, emphasizing the importance of public participation. Rousseff has also suggested that the plebiscite should consider issues like removing unelected substitutes for senators. According to the Brazilian system, all members of Congress have substitutes who can take over their position if they resign, such as to accept a Cabinet position. Rousseff is also pushing for the public to have a say in the rules that allow lawmakers to be elected with the support of voters from different parties. A Datafolha poll showed that 81 percent of Brazilians support the protests for change, with 68 percent in favor of having a plebiscite. However, Rousseff's political opponents believe that the popular vote is a tactic to divert attention from issues like lack of investment in infrastructure and to regain support before the next election. Senator Alvaro Dias of the PSDB, the main opposition party in the Senate, argues that most of Rousseff's proposed reforms are already being discussed in existing congressional bills, and that a rushed plebiscite would be an unnecessary expense for the country. He claims that these issues are not the main priorities for Brazilians and that it is a political distraction. The possibility of a fiasco exists with the plebiscite, which also presents a risk to Rousseff. The PMDB party, a key ally in her coalition government, is hesitant about the idea and prefers reform to be handled in Congress. According to political analyst Andre Cesar, there is concern that the vote may not take place or could lead to unforeseen consequences such as Congress debating the end of presidential re-election. Despite holding a slightly above 50 percent approval rating and being the frontrunner in the 2014 election, Rousseff faces a more competitive race now. Some experts argue that the plebiscite may not be the best way to regain political ground. According to them, Rousseff should prioritize reducing inflation and revitalizing Brazil's economy, which has been stagnant for the past two years. Although smaller protests are still ongoing in Brazil, the main catalyst for the large demonstrations has ceased with the conclusion of the Confederations Cup, a precursor to next year's World Cup. However, there are other challenges to face, as some of Brazil's major labor unions are planning a day of marches on July 11 to advocate for their demands, including a shorter work week.
