The newly christened chairman and chief executive of Altria Group, the tobacco conglomerate that owns Philip Morris USA, Barrington is one of the List's biggest risers. He replaces former Altria chief Michael Szymanczyk in the Top 10, and there's good reason to believe he'll be an even bigger player than his hands-off former boss. In his former role as vice chairman, Barrington, a former partner at the law firm Hunton and Williams, oversaw the company's charitable contributions. Last month Altria gave $10 million to help renovate the Landmark Theater, which will be renamed the Altria Theater next year. Considering the company's size and Barrington's Richmond ties, he very easily could supplant Dominion's Tom Farrell (No. 1) as the city's go-to corporate power broker.
