Jair Bolsonaro was sworn in as Brazil's president on Tuesday after a controversial, polarizing campaign to radically change the center-left path taken by Latin America's biggest country over the last 15 years.

The state of play: Bolsonaro, a provocative, far-right populist, has pledged to purge the country of corruption and crack down on crime — even if that means ignoring democratic norms. Brazil's once-promising economy, which averaged 4% GDP growth between 2004 and 2013, has been crippled by recession and corruption scandals at the highest levels of government.

Millions of Americans who normally vote in person on election day will turn to early voting or mail-in ballots this fall — but that only works if you understand your state's election rules, deadlines and how to ensure your vote is counted.

Driving the news: Axios is launching an interactive resource, built on research by RepresentUs, a nonpartisan election reform group, to help voters across the country to get the information they need.

It's not just emotional buying, real estate agents say: There are smart and strategic reasons that Americans of all ages, races and incomes are moving away from urban centers.

Why it matters: Bidding wars, frantic plays for a big suburban house with a pool, buying a property sight unseen — they're all part of Americans' calculus that our lives and lifestyles have been permanently changed by coronavirus and that we'll need more space (indoors and out) for the long term.
