Lula's commanding position in Piauí for the October 25 second round stems from consistent regional support in the Northeast, reinforced by his first-round performance of roughly 71% of valid votes across all 224 municipalities in the state—the highest share nationally. Local PT-aligned leadership, including Governor Rafael Fonteles, has mobilized mayors and party structures to target an even higher share, building on incumbency advantages and established voter patterns from prior cycles. Recent polling from multiple institutes has shown Lula maintaining 63–70% leads over Flávio Bolsonaro in direct matchups, with the gap reflecting structural preferences rather than late shifts. Only unforeseen national developments, such as major policy reversals or external shocks between now and election day, could realistically narrow this margin in the state.
