At the legislative elections of October 6, 2002, the party won 26 out of 513 seats in the Chamber of Deputies and 3 out of 81 seats in the Senate. Before the 2010 presidential election, PTB participated in the coalition government of former President Luiz In*cio Lula da Silva, and did not field presidential candidates. The party, however, did not support Lula's candidate to succeed him, Dilma Rousseff (herself a former historical PTB/PDT member), as it embarked on PSDB Jos* Serra's failed campaign for President.
