Brazil runoff reverses first‑round momentum

Lula da Silva overturned an unexpected first‑round lead by Flavio Bolsonaro to win the Brazilian presidency in the runoff, defying conventional forecasting and short‑order coalition expectations. The result highlights how rapid realignments among eliminated candidates, turnout shifts and late voter decisions can decisively change ostensibly settled contests. — This matters because it undermines assumptions that first‑round leads are determinative, forcing rethinking of forecasting, coalition strategy, and international reactions to Latin American politics.
