An aide close to Sarah Palin says death threats and security threats have increased to an unprecedented level since the shooting in Arizona, and the former Alaska governor’s team has been talking to security professionals.
Since the shooting in Tucson, Palin has taken much heat for her “crosshairs” map that targeted 20 congressional Democrats in the 2010 mid-term election, including that of Rep. Gabrielle Giffords, who was the main target of Saturday’s attack.
Friends say Palin, a possible 2012 contender, was galled as suggestions of her role in the tragedy have swirled.
Palin responded in detail today to the attacks leveled against her, but while her intentions may have been to shift the blame away from herself, she instead put her in the hot seat again.
