Every candidate has a hidden secret of some wrong that they committed in the past. If they are righteous people and have the desire to act on the peopls’s needs before their own, that makes them better than they were when they committed that wrong.
A worthy candidate rid himself of that sin and rose above it. It no longer controls his interests and should be overlooked by the voters. The wrong is in the debasing of the opposing candidate by he who is running against him.
