Every weekday, Ricardo Brown and Lourdes Ubieta provide Miami with a double dose of politics. Their show on Actualidad (WURN-AM, 1020) is like a cortadito to the cerebral cortex, skipping from local news to national and international politics so easily that before you know it, you've forgone your usual afternoon siesta and actually learned something. Unlike many Hispanic radio personalities, however, they don't ignore Anglo or African-American Miami. Case in point: They interviewed Miami New Times columnist Luther Campbell last year when he ran for mayor. On a recent show, Brown, a Cuban who has won four Emmy Awards and traveled more widely than Anderson Cooper, discussed the Trayvon Martin killing with a leading Miami attorney. In his warm, deep voice, Brown expressed disbelief that Sanford police had threatened journalists reporting the case. "How are they going to arrest you for sending an email to a public figure whose information might be important in a death investigation?" he asked. "As far as I know, asking questions is still legal in the United States." Alongside Brown, Ubieta's rapid-fire, Venezuelan-accented commentary and incisive wit come in handy for fielding the dozens of calls the duo takes on the air every day. Together, they're a doble espreso de noticias instead of that weak, watered-down stuff on other stations.
