Recent legal rulings have created uncertainty around Renan Santos's eligibility to join televised debates ahead of Brazil's October first-round presidential vote. A late-August TSE decision briefly suspended his campaign activities and barred debate participation over undeclared social media accounts, only for the restriction to be partially lifted days later with a compliance deadline. This leaves open the possibility of further holds or appeals before the next scheduled event on September 14. Santos, polling in the low single digits as the Missão party nominee, has already appeared in one sparsely attended debate but lacks free airtime, making additional exposure dependent on court outcomes and organizer invitations. Traders see roughly even odds because any new injunction or procedural delay could exclude him, while swift compliance or favorable rulings would likely clear the way.
