DeSantis, the three-term congressman from Ponte Vedra Beach who is running with President Donald Trump's endorsement, also has almost a 20-point lead among those Republicans who said they have not yet voted but intend to vote in the primary.
DeSantis entered the race in January and largely built his name recognition with near-nightly Fox News appearances.
Sharon Grant said she was planning to vote for Putnam - until Trump weighed in on the race. John McCain. Though McCain was a towering figure who was elected to the Senate by Arizonans six times, the three Republican candidates running to replace his retiring seat-mate, Sen. He beat Putnam, who spent more than twice as much money and ran a robust, even nostalgic, grassroots campaign often featuring down-home picnics attracting big crowds sprinkled liberally with farmers sporting palm-sized belt buckles.
Elected to the U.S. House in 2012 as a Tea Party Republican, DeSantis was a founding member of the House Freedom Caucus, the uncompromisingly conservative and libertarian group derided by critics as the Government Shut Down Caucus.
Republican Carlos Curbelo and Democrat Stephanie Murphy were projected to coast to victory in two of Florida's U.S. House primaries Tuesday night as closely watched matchups in November's battle for the House of Representatives began coming into focus. DeSantis will face the victor in a crowded Democratic gubernatorial primary field led by moderate former U.S. Representative Gwen Graham, the daughter of Bob Graham, a former Florida governor and U.S. senator. He easily won his primary, setting up a showdown with Democratic Sen. Otherwise, Putnam is not within 10 points of DeSantis in any demographic or geographic breakout, except the Tampa market, where DeSantis leads by just four percentage points.
