A Liar Can't Be Trusted

In our personal lives, we have a problem believing people who we know have lied to us. Why should it be any different with politicians? Throughout his campaign, Willard Mitt Romney (aka Wall Street Willie) has lied repeatedly about nearly every issue. The only issue he had remained true to was his desire to give the rich (including himself) a massive tax cut. But in the first presidential debate he even lied about that. How can anyone ever trust this liar again?
