Is he on the way out?

a very popular former president Lula is running against him, and appears to have a sizeable lead.

Lula was in prison on trumped up charges (raised by the bolsonaro administration) and then excluded from running for president because of those charges previously, but they have all been quashed.

Apparently Glenn Greenwald's investigations were critical in getting him released.

If Bolsonaro thinks he is going to lose will he do something desperate? he's already had this guy locked up once to get him out of the way.
it could be an interesting time in Brazil
