The article analyzes the political preferences and values of the groups that organized the protests leading up to the impeachment of Dilma Rousseff, from the Workers’ Party (PT), who was elected to a second term as President of Brazil in 2014. Declaring a fight against corruption, numerous demonstrations, primarily organized through social media, were held against the PT-led government. Corruption was one of the main justifications used to gather crowds in the Brazilian streets. The manuscript presents discursive and ideological elements of these pro-impeachment protesters, collected through in-depth interviews, footage, and face-to-face surveys with participants. The conclusion is that the public came from the middle classes, held values such as support for economic liberalism and anti-egalitarianism, strongly rejected the PT (a leftist party), and represented the early signs of the emergence of the radical right in the country, although not all participants were aligned with this movement. In addition to verifying values and relationships with political parties, statistical tests are presented to measure the causes of anti-PT sentiment in this population
