Ashley Judd is focusing on her family and has decided not to run for a seat in the US Senate.The 'Dolphin Tale' actress - who announced the end of her 11-year marriage to Scottish racing driver Dario Franchitti in January - has announced she has decided not to run for the US Senate seat in Kentucky as she wants to concentrate on her family but did not clarify whether she is trying to repair her marriage.The 44-year-old star wrote on Twitter on Wednesday (27.03.13): "Dear Friends. Thank you for these months of remarkable support & encouragement, for your voices, exhortations & prayers...Regretfully, I am currently unable to consider a campaign for the Senate."I have spoken to many Kentuckians over these last few months who expressed their desire for a fighter for the people & new leader. While that won't be me at this time, I will continue to work as hard as I can to ensure the needs of Kentucky families are met by returning this Senate seat to whom it rightfully belongs: the people & their needs, dreams, and great potential."After serious and thorough contemplation, I realise that my responsibilities & energy at this time need to be focused on my family."Friends close to Ashley and Dario, 39, were surprised by their split as they believed the couple, who got engaged in December 1999 and married in December 2001, at Skibo Castle, near Dornoch, Scotland, were happy together because she was always so supportive of his career.An insider previously said: "When he was introduced, or got a good pole position she yelled and waved her hands in the air and was there to support him in a big way. He is not that outgoing but it seemed cute and like a nice thing for a high-profile actress to be so there for her husband."
