In no way have ex-convicts proven that they can't be trusted, unless everyone who ever broke the law, whether they were convicted or not (nearly 100% of Earth's population) and whether it was a speeding ticket or jaywalking, can't be trusted. The mere fact that it is Republican cretins who have suggested that a criminal record is the measure of a human being is reason enough to reject it. However, it's absurd on its face, a face that looks uncannily like our president.
