In his race against Marco Rubio to become the Republican nominee for one of Florida’s two seats in the Senate, the rich, brash homebuilder Carlos Beruff could not be welding himself more tightly to Donald Trump.

A recent television ad of his attacked Rubio for not being as tough as Trump. He affirmed and then one-upped Trump’s past call for a ban on Muslim immigrants, suggesting a prohibition against anyone from the Middle East except Israel.

His tweets are Trumpian, including this proclamation: “I won’t read a bunch of political crap off a teleprompter.” The Miami New Times crowned him “the Cuban-American Donald Trump.” “Little Trump of Florida,” said the publication Roll Call.

So how’s that working out for Beruff?

Not so well.

Polls put him anywhere from 30 to 60 points behind Rubio in the primary, which takes place Tuesday. He trailed by double-digit margins even before Trump wanly and dutifully signaled support for Rubio earlier this month.
