Do you not consider the use of another countries passport, as an adult, and travel to countries where Americans were not allowed to travel, an issue to be considered when evaluating?
Seems to me that if a person does this he has become a participant of the citizenship his parents have declared after adoption. Personal declaration of citizenship?

The only issue that would potentially disqualify him for the presidency is his citizenship at birth, or whether he has subsequently forfeited that citizenship if it existed. The commission of a felony or felonies in the past can’t possibly have anything to do with his eligibility to serve. At least felonies for which he has not been convicted.
Felonies would go a long way toward discrediting his character, but being a felon has been shown to be negated by skin color.
