Hillary is no more a liar than any other Politian (weapons of mass destruction anyone?)
When former President Bush made the statement about WMD's in Iraq, that was done through faulty intelligence and incorrect deductions made from the intelligence it did have; hardly a deliberate lie. Many politicians during that time (both Republican and Democrat) ascertained that after Hussein kicked out the UN inspectors (the inspections setup by then President Clinton), that he still had stockpiles of WMDs and was continuing research into their production. There was debate as to whether the supposed evidence of WMDs warranted use of unilateral force, but no one was debating about their supposed existence prior to going into Iraq. Thus Bush "lied" about WMDs as much as then Senator Clinton did:
"In the four years since the inspectors left, intelligence reports show that Saddam Hussein has worked to rebuild his chemical and biological weapons stock, his missile delivery capability, and his nuclear program. He has also given aid, comfort, and sanctuary to terrorists, including Al Qaeda members, though there is apparently no evidence of his involvement in the terrible events of September 11, 2001.
It is clear, however, that if left unchecked, Saddam Hussein will continue to increase his capacity to wage biological and chemical warfare, and will keep trying to develop nuclear weapons. Should he succeed in that endeavor, he could alter the political and security landscape of the Middle East, which as we know all too well affects American security." -- Senator Clinton on resolution to use force in Iraq
When Mrs. Clinton said that the attacks in Benghazi were caused by an on-line video:
"Some have sought to justify this vicious behavior, along with the protest that took place at our Embassy in Cairo yesterday, as a response to inflammatory material posted on the Internet"
that was indeed a deliberate lie as evidenced by her own words to the Egyptian president the very next day:
“We know the attack in Libya had nothing to do with the film. It was a planned attack — not a protest.”
True, politicians do lie more often than you'd find in the general public -- usually in order to get elected -- but for Mrs. Clinton, her lies are much more devastating and can have worse consequences for our country.
