Think Progress explores the subject. It notes the Miami Herald's interview of a prominent Miami-Dade Republican. Cuban-Americans make up a critical part of the Republican base in Florida and they are increasingly unhappy with the xenophobia expressed by many in their party.
GOP lobbyist and fundraiser Ana Navarro, who dropped her support for McCollum after he proposed a law “tougher” than the controversial immigration bill in Arizona, said McCollum’s stance lowered his margin of victory in Miami-Dade — and kept many Hispanic voters from going to the polls.
“I think he can blame [immigration],” Navarro said. “I think if you speak frankly with McCollum himself, he would admit it was a mistake.”
It was McCollum’s sudden support of an Arizona-style immigration bill — after originally distancing himself from that kind of legislation — that hurt him, said Carlos Curbelo, Republican in a runoff for a Miami-Dade School Board seat.
“That change took away much of McCollum’s credibility,” he said, while adding that Scott, who has attacked McCollum’s immigration proposal, faces a difficult task ahead in trying to woo Florida Hispanics.
