Lula also benefited from a drop in blank and null votes, which fell from 4.5% to 3.2%, marking the lowest share of spoiled ballots in a runoff election this century. The decline in blank votes was most pronounced in the Northeast. Preliminary data indicates Lula also won most votes from third-party candidate Cury, while voters for Caiado and Renan Santos split roughly 40% to Lula and 50% to Flavio.
