Stonyfield Yogurt CEO and Concord resident Gary Hirshberg still has not announced whether he will run in one of the most highly watched US Senate race in 2008.
Hirshberg, a Democrat, said he will make up his mind by today, March 5. None of his associates were aware of any decision and he did not return a phone call to the Globe.
Currently two Democrats -- Portsmouth Mayor Steve Marchand and Bow activist Katrina Swett Ė have filed papers to challenge Republican Senator John E. Sununu.
Many Democrats see Hirschberg as a potentially strong candidate in the crowded Democratic primary, given his liberal politics and deep personal financial resources.
The Democratic National Senatorial Committee has said the New Hampshire race was among the top three they were targeting in 2008.
Last week, the conservative Club For Growth took an usual step of endorsing Sununuís re-election in an attempt to raise money for him. Historically, the Club for Growth only targets money where there is a contested Republican primary, and Sununu isnít expected to face a primary challenger.
