BRASÍLIA — “I wasn’t born to be president,” Brazil’s president, Jair Bolsonaro, said during a recent address at his official residence. “I was born to be a soldier.”



The tone used by Mr. Bolsonaro, a former army captain, was lighthearted. But the message underscored how turbulent his first few months as president have been.

In just over 100 days in office, he has used up much of his political capital, with little progress on crucial issues to show for it. Brazilians are growing impatient.

The president, a right-wing populist, was swept into office with an expansive mandate for change by voters fed up with political corruption, violence and the lingering effects of a deep recession.
