The uncertainty is primarily the result of pressure from the street and a mass movement in Brazil, Dominguez said. Rousseff is mobilizing, traveling around the country, staging rallies and garnering more support than she had when was a sitting president.
"She is becoming extremely popular. Although she went down the polls at some point in past, now she has reinvigorated herself."
"The situation is radicalizing quite enormously, and I imagine, were they to impeach her definitely, the country is going to explode."
The senators face a problem, as many are known to be corrupt and, if they do not impeach Rousseff, they are likely to face charges and investigations, Dominguez said. Moreover, Rousseff has said that she will initiate a general election to seek "new blood" in both the Congress and the Senate if she is reinstated.
"You can imagine the fright [of] the people who are in the position of privilege right now," Dominguez said.
Yet, if the enormously popular Rousseff is impeached, the current neoliberal interim government will find itself isolated, Dominguez said, as many countries "will come up and say they will not recognize the government coming out from this undemocratic process."
Either way, Brazil is in for a rough ride.
