Jorge Ramos anchors the top-ranked newscast on Spanish-language TV, Noticiero Univision, alongside Maria Elena Salinas. Sometimes called "the Spanish-language Walter Cronkite," Ramos has been a vocal -- and influential -- proponent of an immigration overhaul. (In recent summers, Ramos' network Univision has topped the prime-time TV ratings for all networks in the U.S. -- English- and Spanish-language -- among viewers 18 to 49, as Mandalit del Barco reported Tuesday.)
