Brazilian President Jair Bolsonaro is stepping up his aggressive rhetoric in the run-up to Brazil’s general election, a strategy that is likely to rally his radical base but risks alienating centrist voters.

At an agribusiness convention on Wednesday, he promised to further ease laws that restrict the ownership of firearms if re-elected in October and called on his supporters to arm themselves.

"Our generation can’t be remembered in the future as one that had a chance to do something but cowered before two or three people,” he said in a not-so-veiled reference to top justices who are presiding over the country’s electoral court. "Buy your weapons, that’s in the bible.”

Trailing former President Luiz Inacio Lula da Silva in major opinion polls, the former army captain continues to spread conspiracy theories about the integrity of Brazil’s electronic voting system. Unsubstantiated allegations of voter fraud are usually accompanied by insinuations that he could mimic Donald Trump and try to overturn the result of the election in case he’s defeated — a strategy that costs him votes from moderate Brazilians, according to surveys.

At Wednesday’s convention, he cited Argentina, Venezuela and Uruguay as examples of what’s going wrong in the region, and said voters need to make sure Brazil doesn’t follow the same path. "The armed forces are the last obstacle to socialism,” he said.

On Monday, he gave a five-hour long interview on social media, where he renewed attacks on electoral authorities, Latin American left-wing presidents and minorities in general.
