On Sunday,the Senate's No. 2 Democrat, Dick Durbin, cited the Palin map as a sign of the "toxic rhetoric" that has come to define national politics in recent years. He said he was not making a direct connection between Palin and the shootings. Palin offered her condolences after the massacre Saturday in a brief message on Facebook and has said little else of it. But she did email conservative radio host Glenn Beck, who read part of their exchange on the air Monday morning, per Politico's Keach Hagey. "I hate violence," Palin wrote Beck. "I hate war. Our children will not have peace if politicos just capitalize on this to succeed in portraying anyone as inciting terror and violence." Still, Palin has become a focal point in the debate over heated rhetoric, and her response is likely to be a defining moment in her political career. One informal but telling sign of the potential stakes for Palin: According to Facebook, the top question dominating debate on the site over the weekend was "Is Sarah Palin to blame?"
