I trust other's judgement and they do what is best as they see fit.
I think a greater moral question might be allowing a president Hillary Clinton.
One can live in a red state and say, I wouldn't vote for Trump because I have moral questions and one's vote really may not affect things, one may live in a blue state and there are similar circumstances, where one's vote won't affect it voting progressive.
And then, one may live in a swing state.
And besides all of that, at times, I'm voting for a leader, not sainthood for someone, not judging so much as to whether a person committed adultery numerous times in the past and things like that, maybe as much as 12 years ago or longer and has since, refrained from that behavior.
How about George Patton? He cussed. Would I not then, want him to be a leader of our troops in a crucial situation like World War II?
It's for us all to decide.
Where is the line in morality? One can question every president and I mean every single one including Reagan.
