Now I see that it appears that Van Susteren's husband played a somewhat significant role in the presidential career of Palin. (h/t Think Progress)
John Coale: Coale, a well-known Washington lawyer and the husband of Fox News Channel's Greta Van Susteren, drew national media attention when he endorsed Sen. John McCain's presidential bid in protest of the way in which Sen. Hillary Rodham Clinton, who he backed in the primary, was treated. Coale, in an interview with the Fix, described himself simply as a "friend" of the Alaska governor but acknowledged that he suggested she start a leadership PAC and helped her navigate through some of the questions surrounding her family that lingered after the campaign. Others familiar with Palin's political team insist that Coale has far more power than he is letting on -- essentially helping to run Sarah PAC. Coale demurred on that front, noting only that he talks to Palin regularly and that she is a "fascinating person" who is "definitely not what the right thinks or the left thinks."
