It doesn't matter. Null votes don't count. They should have voted for the other guy if they didn't like Bolsonaro.
Mandatory voting is just another useless attempt to mask the fact that today's politicians are not actual leaders but rather worthless reality TV personas. Like in Ukraine where people picked an actual actor in an attempt to mock the worthless political class. It's typical Eastern European absurd humour. Adam Curtis' HyperNormalisation documentary explains it quite well.
