Jorginho Mello, the incumbent governor of Santa Catarina seeking reelection with the Liberal Party, maintains a commanding lead in recent polling that underpins trader consensus on his strong position. Surveys conducted in late September by Quaest and Paraná Pesquisas placed him at 54% to 58.8% of first-round vote intentions, well ahead of João Rodrigues and Gelson Merísio, with approval of his administration reaching 78%. His decision to step away from official duties for the final campaign stretch has coincided with stable support levels that suggest a possible outright win on October 4. Opposition candidates remain fragmented with single-digit or low-teen support, limiting coordinated challenges. Shifts in undecided voters or turnout patterns in the final days could still influence the margin, though current data shows limited volatility.
