I did an essay the other day about how Brazil's leading presidential candidate sits in prison, without any evidence of his wrongdoing.
According to polls, he has almost twice the percentage of the 2nd and 3rd place candidates combined.
With Luiz Inácio Lula da Silva possibly blocked from the ballot, this is the de facto leading candidate.

Until recently, Bolsonaro was on the margins of Brazilian politics, a seven-term congressman who occasionally featured in the headlines, mostly for making offensive remarks about the LGBTQ community, women and Afro-Brazilians.
...Bolsonaro is now considered a serious presidential contender, despite a heavily tainted record that includes telling a congresswoman in 2003 that she did not deserve to be raped by him.
He also once stated he'd be incapable of loving a gay son.

Last year, he caused an outcry by declaring that in his view the inhabitants of Afro-Brazilian communities known as quilombos are "not even good for breeding any more."

Wow. Nice guy. The kind of guy you want to invite to your party.
If that wasn't enough, he doubled-down on his racism yesterday.

Jair Bolsonaro, a favorite in the Brazilian presidential race, said his country owed blacks no debt because of slavery and pledged to cut back affirmative action policies.

"What debt of slavery? I never enslaved anyone in my life," the former Army captain said in an interview on TV Cultura late on Monday. "Look, if you really look at history, the Portuguese didn’t even step foot in Africa. The blacks themselves turned over the slaves.”

And yet, that isn't the worst part.
His racism, sexism, and homophobia are bad, but his authoritarian tendencies are flat out scary.

If elected, he reportedly intends to appoint military officers in his cabinet, deepening fears among his critics that he has authoritarian leanings.

Bolsonaro's admiration for the army extends to the country's repressive military dictatorship that ruled from 1964-85. He describes this to NPR as "a very good" period, that "stopped Brazil [from] falling under the sway of the Soviet Union."

That "very good period" included the slaughter of thousands of leftist political dissidents.
Will we see a repeat coming?
Brazil's military seems to be saying "elect our guy, or there will be tanks in the streets".

“We are in a critical moment, walking right up to the razor’s edge,” said Antonio Mourão, a four-star general who recently retired after suggesting last year, while in uniform, that a military intervention might be necessary to purge the corrupt ruling class. “We still believe that the electoral process will represent a preliminary solution for us to shift course.”

In other words, an election without Lula would be a disaster.
The U.S. business media has repeatedly said that Lula can't run, but then I've seen this.

According to current Brazilian law, Lula can still put himself forward as a candidate for the presidential elections despite being held in prison. His candidacy can be contested until the 15th of August, but due to the duration of the proceedings of the Supreme Electoral Court, there would not be enough time to remove his name from the ballots before the election date.
Now there is a possibility that the court approves Fachin’s procedure and prohibits Lula’s presidential candidacy. It is possible that a political negotiation takes place in order to free Lula so that he can not only participate and win, but also assume the powers of the presidency. It is also possible that he is freed and loses the elections.
