How can you tell when a politician is lying? When his lips are moving:
“Thank you for contacting me to express your opposition … to the early use of military force b the US against Iraq. I share your concerns. On January 11, I voted in favor of a resolution that would have insisted that economic sanctions be given more time to work and against a resolution giving the president the immediate authority to go to war.” –letter from Senator John Kerry to Wallace Carter of Newton Centre, Massachusetts, dated January 22 
“Thank you very much for contacting me to express your support for the actions of President Bush in response to the Iraqi invasion of Kuwait. From the outset of the invasion, I have strongly and unequivocally supported President Bush’s response to the crisis and the policy goals he has established with our military deployment in the Persian Gulf.” –Senator Kerry to Wallace Carter, January 31 
Kerry Lied. People Died.
