RIO DE JANEIRO — A polarized nation. A right-wing populist casting doubt on the electoral system then refusing to concede. A riot by his supporters in the capital aiming to keep him in power.
This isn't just the story of Donald Trump, but also that of Brazil's Jair Bolsonaro. The Western Hemisphere's two largest democracies faced similar challenges in 2020 and 2022, respectively, but their institutional responses have been dramatically different.
Brazil moved swiftly to rule Bolsonaro ineligible for office until 2030, a penalty that could be extended by ongoing criminal investigations. In Washington, however, Republicans in the Senate helped acquit Trump in an impeachment trial that would have prevented him from seeking the presidency again. And the legal process unfolded slowly as the courts grappled with the novelty of prosecuting a onetime president.
The different approaches to Bolsonaro and Trump amount to a case study of how democracies attempt -- and sometimes struggle -- to hold their most powerful leaders to account. The examples are being closely watched at a time of rising concern that democratic governments around the world are destabilizing.
Fresh memories of authoritarianism
Brazil's democracy is young, having emerged from military dictatorship four decades ago. The ghost of authoritarianism, which led millions to watch the new movie ''I'm Still Here,'' continues to haunt many Brazilians — although Bolsonaro, an outspoken cheerleader of the past regime, still won his first presidential race handily.
By contrast, the U.S. of 2020 had no memory of homegrown authoritarianism, which ''gave rise to a lot of naivete,'' according to Steven Levitsky, author of ''How Democracies Die'' and director of the David Rockefeller Center for Latin American Studies at Harvard University.
"Part of the story without question is that a number of key players — I'm thinking about non-Trumpist conservatives on the Supreme Court — never really thought Trump represented a threat and didn't act accordingly, didn't act like the Brazilian court,'' Levitsky said. ''There are members of the U.S. establishment that still just cannot imagine that democracy could fall apart.''
