Jim Schwartzel holds the lead in the August 18, 2026, Republican primary for Florida's 19th Congressional District, an open seat, as the only candidate with deep local media ties through Sun Broadcasting and a narrow edge in the most recent public poll from June. Self-funding and donor support have shaped the field, with Jim Oberweis committing nearly $5 million in personal loans and Catalina Lauf raising nearly $1.5 million without self-funding, though both trail Schwartzel in local name recognition and early polling. The crowded ballot, including Madison Cawthorn and others with lower support, has kept the race fragmented with high undecided shares. Limited polling since June and heavy spending in the final stretch reinforce trader consensus around Schwartzel's positioning while leaving room for late shifts before primary day.
