GOP Sen. Marco Rubio is making headway in national polling in his White House bid, but he still hasn't won over some conservative media commentators who are fuming about his past support of immigration reform.

"So many of these guys were on his side until he made that one big error in their eyes," Rich Noyes, a research director at the conservative Media Research Center, tells The Hill.

"Republican primary voters are conservative talk radio listeners, and what they hear has a reinforcing affect. It helps immensely to have them on your side, and immigration is his biggest problem with that."

Laura Ingraham, Michelle Malkin and Ann Coulter are so far staunchly opposed to Rubio over the issue of amnesty – and are telling their audiences he'll fold on the issue if elected president.

Case in point: Rubio's backing by billionaire GOP donor Paul Singer, a backer of immigration reform, the pundits say.

"What worries me really about Marco Rubio is Paul Singer, his big benefactor, who is [for] open borders, [is] terrible on social issues and, as far as I can tell, is more concerned about the globalism agenda than the issues that are the best for the American people," Ingraham said on her show this week. "That's my concern."

She also hammered the Florida senator in an interview with rival presidential contender New Jersey Gov. Chris Christie, asking him if Rubio's position that the executive orders on amnesty can't easily be revoked should disqualify him.

"I don't know why anyone would want to have someone who is not going to enforce the law as the chief law enforcement officer of the United States," Christie responded.

Malkin also has accused Rubio of being in the pocket of "his amnesty-peddling campaign donors."

And Coulter has slammed Rubio for devoting "his entire Senate career to pushing amnesty."

The conservative news website Breitbart also has hit Rubio for his association with Singer.

Yet Rubio has made "considerable inroads among some of the biggest names in talk radio and TV, including Glenn Beck, Rush Limbaugh, Mark Levin and Fox News host Sean Hannity, The Hill reports.

Still, Noyes tells The Hill, "They don't forget."

"The House leadership thinks it's gonna be Jeb [Bush] or Rubio," Limbaugh said on his show last month.

"The dream: Jeb or Rubio in the White House; Ryan Speaker of the House. Then in the first 12 months of the Rubio or Jeb administration, first 12 to 18 months, the donor-class agenda is implemented, including amnesty and whatever else they want. That is the objective here. That's what I think all this adds up to."
