Sunday's results underscored how far the former president has come in building a political dynasty. As Flávio Bolsonaro, a far-right senator, heads into the runoff against Lula, congressional races secured seats for Michelle Bolsonaro, Carlos Bolsonaro and one of Jair Bolsonaro's brothers.
Michelle Bolsonaro, 44, the former first lady, ran for public office for the first time and was elected senator. She divided her campaign between the trail and caring for her husband, who is serving a sentence under house arrest for attempting a coup.
Carlos Bolsonaro, 43, regarded as the most radical of the siblings, was also elected senator for the first time. He ran his father's social media accounts and was indicted by federal police for leading a so-called hate cabinet that spread fake news and attacks on political opponents.
Few in the family have spent much time working outside politics since the patriarch entered public life four decades ago, but the offices they now hold have had a significant upgrade. The results give the family its strongest electoral position yet as it contests the presidency.
