Catalina Lauf leads the FL-19 Republican primary market at 51% because her fundraising has accelerated sharply, with over $541,000 raised in the first quarter of 2026 and nearly $975,000 total, alongside prior Trump administration experience and conservative positioning in this open-seat race. Jim Schwartzel follows at 13.6% on the strength of his local business ties and campaign account exceeding $1.7 million in receipts, while Jim Oberweis at 12.9% and Madison Cawthorn at 10.5% draw from prior elected roles and self-funding but trail in recent momentum. The August 18 primary remains months away in a deep-red district, leaving room for shifts from endorsements, additional spending, or candidate withdrawals among the crowded field.
