CLINTON: Ahead of Clinton's speech today about terrorism, one of us writes that "the former secretary of state is walking a delicate balancing act between a Republican presidential field that is proposing an aggressive and sometimes controversial response to fight ISIS and the policies of President Barack Obama who is losing trust among Americans that he can keep them safe."
