Catalina Lauf leads trader consensus in the Florida 19th Republican primary at 52 percent amid endorsements from sitting members including Anna Paulina Luna, Burgess Owens, and Jim Banks, plus her prior Trump administration role, which have positioned her ahead in a crowded August 18, 2026 field. Jim Schwartzel and Jim Oberweis trail at 18 and 12 percent respectively, reflecting their stronger early fundraising totals exceeding $1 million each in recent FEC filings despite less prominent national backing. Madison Cawthorn holds 10 percent on name recognition from his prior congressional tenure, while Spencer Roach and Bob Rommel remain at single digits in a race where consolidation and additional quarterly reports could shift positioning before primary ballots. The open seat created by Byron Donalds’s gubernatorial bid keeps the contest focused on these dynamics.
