Pollster Frank Luntz acknowledges that he took money to help shape Sen. Marco Rubio's (R-FL) political career, a fact that he did not disclose while praising Rubio on Fox News and on social media. ... Luntz admitted to Breitbart News that he once accepted payment to work for Rubio. “Yeah, nine years ago,” Luntz admitted. “Nine years ago.” Luntz defended the supposed impartiality of his post-debate focus groups.
