On the eve of Rousseff impeachment trial, PR war waged over former Brazilian leader

In an abandoned music hall, in the dark, about 20 people live in tentsamid old beer cans, artists posters and other detritus of concerts past.They've been here since the beginning of August,since they got kicked out of the last place they occupied.

Teacher Lisa Brito, 36, re-arranges her tent fly in the orange glow of a distant stage light.She says this encampment is a statement.Everyone here has their own cause labour rights, the poor, people of colour, the arts.But they have one goal: They want their president back.

"The opposition was unhappy with (Dilma) Rousseff's victory in the 2014 election," Britosays. "And ever since then they've been trying to bring her down."

Rousseff to be tried by Senate

The final phase of Rousseff's impeachment the endgame of a process that began late last year startsfour days after the Olympic Games ended, when the trial session starts in the Senate on Thursday. Rousseff herself will only take the stand the following week on Aug. 29.

The trial's expected to last until the 31st, and if two-thirds of the senators vote for impeachment, as is widely expected, Rousseff will be permanently removed from office and barred from running for the next eight years.

Now, with Rousseff's fate hanging in the balance, both sides are making a last attempt to change public opinion any way they can.

Supporters likeBrito believeRousseff's transgressions moving money around to mask her government's budget deficit are fairly minor compared to the scandals that have seen more than half the Senate investigated or charged.

"The fiscal creative accounting that she's accused of is something that happens at the federal level, the state level, in various spheres of government," Brito says. "So it's not unique to her."

That's why the music hall is covered in graffitiaccusing interim president Michel Temer of orchestrating a "golpe;"the process of impeachment, Brito says,is "a parliamentary coup."

Ridiculous, says 32-year-old marketer Renan Santos, who's standing in a massive public square in the Old Port area, looking for tourists to interview.

"Our left says it was a coup! It was a coupd'tat," he says, mockingly, to a Dutch couple he stopped as they were sightseeing.

Santos is one of four young menwho areshooting a video for social media,asking foreigners what would happen if their head of state got caught fiddling with the numbers.

Jail for fudging the figures

"They would go to jail for sure," the Dutch man says.

"Certainly," echoes his wife.

That was the answer Santos was looking for.

"Our reputation internationally became really low, (Rousseff)caused lots of problems, and we live in a crisis caused by her responsibility," Santos says. "And for sure we have corrupt politicians involved in the scandal that belong to all parties, but it doesn't make her less guilty."

And on this both sides generally agreethe impeachment process so far has been legal and constitutional.

"Right now we see the end of the fight and the Brazilian people won," Santos says. "And definitely this is like a very nice, democratic way to end the 'Brazilian spring.'"

Temer's government called 'racist'

But opponents of the interim president are alarmed by his government's rightward shift.Temerhaswatered down protection for workers andeliminated departments that protect women and the poor.His new cabinet, says Julio Barroso, isall male and all white.

"It's a racist government," he says. "As a black Brazilian, I'm very worried. We're going to be hurt the most by this, not just by the Temer government but by what could come after it."

Barroso opens up a massive, tattered sheet of paper torn from a flip-chart easel and spreads it over the old DJ's table at the back of the concert hall.It's covered in phone numbers:more contacts for the next protest. The next call-to-action is imminent.

If Rousseff is impeached, he says, these occupiers will be demanding new elections, to prevent Temer from consolidating power. He's already begun, Barroso says earlier this month Temer transferred control of Brazil's intelligence agency to the military.

"I lived under the dictatorship," he says. "People were terrified of speaking out against the government, and that's the direction the Temer government wants to take us."

I ask Brito how long she plans tolive in that dark concert hall.

"We don't leave,until Temer leaves," Brito says.

Or, much more likely, until they're kicked out.
