A person's character does make a difference as to whether you believe what he/she says or not without actual proof of his/her actions.
Some use religion as a part of the character judgement process. (among other things)
The problem is the 3 Presidential choices are trying to sway the voters opinions of their characters by saying things that they ARE CLEARLY AGAINST BY THEIR PAST ACTIONS.
This years election choices are like sitting on a toilet with your feet in the water looking for the best turd to run the country.
