There is no consensus amongst the opposition, so if Bolsonaro were to be impeached now it is likely to be a long drawn out procedure that may not go anywhere and take more time away from more pressing matters. There was a major call for his impeachment in March 2020, but there was no political will to carry this through, and the support for his impeachment was limited to a minority, with Bolsonaro’s supporters becoming only more mobilised by the calls for his resignation. Today polls show that Bolsonaro’s impeachment remains just as divisive, with only a slim margin of 2.7% in favour of impeachment (47.7% for, 45% against, and 7.3% not sure). Impeachment at this moment would be too divisive, would probably fail, and would be too costly in terms of political capital.
