Brazil is headed for a runoff between center-left President Luiz Inácio “Lula” da Silva and far-right senator Flávio Bolsonaro, after the latter took the lead in the first round by nearly two percentage points last Sunday.

The party won the most gubernatorial races in the country, with outright victories in five states. That number could rise to seven after runoffs in the states of Amazonas and Rio de Janeiro.

For Paulo Niccoli Ramirez, a political science professor at the Higher School of Advertising and Marketing (ESPM) and the São Paulo School of Sociology and Politics Foundation (FESPSP), Bolsonaro’s win “demonstrates the strength of the Bolsonarists, their use of social media, and their ability to sway voters’ thinking through Instagram, Twitter or Facebook.”

Can Lula turn the election around?

Although the gap between Da Silva and Bolsonaro in the first round was less than two percentage points, the analysts........
