Facing the scenario of intense polarization in the second round, the group that was the biggest protagonist in the political debate on Twitter in the first phase of the campaign has faded away. On one hand, with an anti-Bolsonaro discourse, the pink group, which garnered up to 60% of the profiles and interactions in the first round, continues to have a high percentage of accounts, but now has a much smaller volume of participation on the network and mobilizes less discourses as a consequence. From Thursday (11) to Sunday (14), with 5.4 million retweets about the presidential hopefuls – the 13 who participated in the first round –, the pink group dropped to only 10.7% of the retweets, made by 34% of the profiles participating in the discussion.

Profiles’ support for the political fields

Blue: Jair Bolsonaro’s support base

Pink: Anti-Bolsonaro profiles that are not aligned with any party

Red: Fernando Haddad’s support base

Purple: Includes profiles of yellow and orange groups

Yellow: Includes profiles that shared statements and memes related to candidate Cabo Daciolo

Orange: Includes profiles supporting João Amoêdo, Marina Silva and Geraldo Alckmin

Gray: Accounts outside of debate

On the other hand, the blue group, which supports Jair Bolsonaro, saw a considerable increase in the volume of retweets made by its members: it had 24.5% of the profiles (they were 18.6% in the week before the first round). Fernando Haddad garners more profiles today (35.5%) but has only 36.3% of the interactions identified.
