Brazil's election ended with Lula declared the winner under circumstances that critics say were rigged, a troubling sign for institutional trust and for Brazil's conservative movement.

• Lula pulled off a huge swing in the final vote count, overturning a big lead his opponent Flavio had going into the last stretch.
• Brazil's Supreme Court extended voting hours only in areas that favored Lula, while keeping other areas closed, fueling fraud accusations.
• Four Supreme Court seats were up for grabs under the next president; with Lula winning, the court is expected to tilt heavily in his favor for years to come.
• The shift matters beyond Brazil, since it was seen as the last major right-leaning holdout in a South America that had been trending conservative.
• Bolsonaro's side says it will challenge the results, but past post-election protesters in Brazil have faced harsh, lasting prison sentences, which may discourage unrest this time.

Outlook: Expect a legal challenge from Bolsonaro's camp, but little chance of it succeeding given Lula's control over the courts and government, pointing to a sharp leftward and more regulated turn for Brazil's media and tech policy.
