There's no real ideology behind flavio bozo, he has the mentality of a petty criminal who got too much money and is trying to avoid being caught. He has managed that thus far, despite many spotlights showing how rotten he is.
Then again, the largest political force in Brazil for the past 20 years has been antipetismo, simply being against PT (Worker's party). For a lot of people, anything is better than PT and Lula. Democracy is a perpetual risk of putting asinine demagogues in power.
