I am sure that every candidate had dishonest moments in their lives. We all have.
But, attributing "dishonesty" as a character trait of any democratic candidate is nonsense and unsupported.
On a scale of 1 to 10 (10 being a pathological liar), Bill Clinton is a 3 at best. Nixon probably a 3.5.
Trump is a 15.
Any current candidate is < 1.2
