A candidate voters believe in equate to a person who have no character, integrity, and no values. That will only push conservatives not vote even more.
The perception of the Republican Party is that they are stuck up and have no compassion and have little empathy toward their fellow man. It isn't about a candidate it is about the GOP as a whole. Until the RP realized that and changed their ways will they be able to get the common man and minority to believe in them.
