Sitting in a hotel conference room of a Scottsdale, Ariz., resort, Mike Huckabee kibitzed with a few reporters Friday about issues ranging from the Iraq War to the suspension of New England Patriots quarterback Tom Brady.

But when the talk turned to whether undocumented immigrants should have a path to U.S. citizenship, the former Arkansas governor clammed up. “Until we have a secure border,” Huckabee demurred, “there isn’t any other discussion for us to be having.”

Huckabee isn’t the only Republican presidential candidate to dodge the topic lately. As the 2016 race ramps up, GOP candidates are increasingly skirting the specifics of immigration policy. It’s a trend that threatens the party’s hopes of reclaiming the White House.

Routed in the battle for Hispanic voters in 2012, the Republican Party promised to speak differently about immigration this time. But the need to repair its relationship with Latinos has collided with its candidates’ need to court the conservative activists who dominate the GOP nominating contest. As a result, many of the party’s presidential hopefuls don’t want to divulge the details of their positions on an issue with major political and policy ramifications.

To discern the differences between the candidates on immigration, TIME distributed a brief survey to declared and likely White House hopefuls. The questions focused on the fate of the estimated 11 million undocumented immigrants currently in the U.S., a subject at the heart of the bipartisan debate over comprehensive immigration reform:

Do you support an eventual pathway to citizenship for undocumented immigrants currently residing in the U.S., and if so, under what conditions?

Do you support any government benefits, such as in-state college tuition, for undocumented immigrants who were brought to the U.S. as minors?

Some likely GOP candidates offered clear and succinct answers. Former Pennsylvania Sen. Rick Santorum was a “no” on all four, according to his spokesman. South Carolina Sen. Lindsey Graham, one of the architects of the Senate’s bipartisan attempt to overhaul U.S. immigration laws in 2013, stuck by his support for a path to citizenship under detailed conditions. “Citizenship need not be mandatory, but it needs to be an option for those who are qualified,” said Graham spokeswoman Brittany Bramell. Graham also backed a process to give legal status or citizenship—along with government benefits like in-state tuition—to minors brought to the U.S. by their parents.

But the majority of the field offered muddier responses, or declined to answer at all. Louisiana Gov. Bobby Jindal was one of several to argue the debate should be postponed until the southern border is secured.

“Any discussion about dealing with who is already here is counterproductive until the border is secure,” Jindal told TIME in a statement issued through his spokesman. “Any attempt to deal with the millions of people who are currently in this country illegally prior to securing the border is illogical, and is nothing more than amnesty.”

Asked about a pathway to legal status for undocumented workers who met certain conditions, Jindal dismissed it as “a hypothetical conversation.” As for legal status or citizenship for those brought to the U.S. as minors, Jindal turned the focus to Obama. “A serious discussion about those individuals is just not possible right now because of the reckless policies of this administration,” he said. “This President has done everything he can to encourage illegal immigration.”
