HOMESTEAD, Fla. — Cipriano Garza says Rep. Carlos Curbelo is “a decent man, a family man.” He lauds the South Florida Republican for defiantly pushing his party to protect young “Dreamer” immigrants from deportation.

Founder of a nonprofit that helps farm workers, Garza happily hosted Curbelo at a reception honoring high school graduates last week at the massive Homestead-Miami Speedway. But his praise came with a warning about this November’s elections.

“He better do what’s right for the community,” said Garza, 70, himself a former migrant laborer. “If not, he can lose.”

Across the country — from California’s lush Central Valley to suburban Denver to Curbelo’s district of strip malls, farms and the laid-back Florida Keys — moderate Republicans like Curbelo are under hefty pressure to buck their party’s hardline stance on immigration. After years of watching their conservative colleagues in safe districts refuse to budge, the GOP middle is fighting back — mindful that a softer position may be necessary to save their jobs and GOP control of the House.

“Members who have priorities and feel passionate about issues can’t sit back and expect leaders” to address them, Curbelo said. “Because it doesn’t work.”

Curbelo, 38, is seeking a third term from a district that stretches from upscale Miami suburbs to the Everglades and down to eccentric Key West. Seventy percent of his constituents are Hispanic and nearly half are foreign-born. Those are among the highest percentages in the nation, giving many of them a firsthand stake in Congress’ immigration fight.

Curbelo and Rep. Jeff Denham, R-Calif., whose Modesto-area district thrives on agriculture powered by migrant workers, have launched a petition drive that would force House votes on four immigration bills, ranging from liberal to conservative versions. Twenty-three Republicans have signed on, two shy of the number needed to succeed, assuming all Democrats jump aboard.
