Recent polling in Florida's 19th congressional district Republican primary shows Catalina Lauf and Jim Schwartzel essentially tied in the low-to-mid teens with substantial undecided voters, while Jim Oberweis trails further back. Recent endorsements from sitting Republican U.S. representatives Greg Steube and Kat Cammack have given Lauf modest momentum in the final days before the August 18 vote. Fundraising totals favor several top contenders, including Lauf and Schwartzel, amid a crowded field that includes former members of Congress. The tight trader consensus on Polymarket reflects this competitive environment, where small shifts in turnout among conservative voters or additional late-cycle support could widen the gap between the leading candidates.
