Another user here talked about this, there were some other reasons. Most of them are selfish, I think the main one was that the second round of the municipal elections, Lula probably did not go to the meeting and vetoed Venezuela and Nicaragua (Actually I could not find articles about Nicaragua though, and someone said it was not even the final list, it was just a pre-list) so his own party and coalition did not have more problems because of Lula's meeting with Putin and Maduro (They did ok in this election, I think they just had a big defeat, but to be honest it was a difficult election for Lula's candidate to win. A pleasant surprise was the victory of the Workers Party in Fortaleza and in the South, before a very pro-Bolsonaro region, but which has a large presence of the left due to rural workers), the Workers Party having an unexpected runoff against the Liberal Party (Bolsonaro's party) in the Center-West, a region that the Workers Party was never strong.
