When’s the last time Deceptive Donnie was asked if he cheated on his current wife?
Do you think he would answer truthfully if he did?
Would that make any difference to you?
Why should any candidate be asked this question?
Are there any limits to the admissions of a candidate’s past sins you would demand an answer to?
Do you believe in forgiveness?
Don't know, but I'm sure he'd answer the question in a more straightforward way than Ted Cruz did. Of course, virtually any answer would meet that qualification.
Of course, Donald Trump doesn't try to deliberately cultivate an image that he's some kind of squeaky clean devout family man Evangelical.
Do you think he would answer truthfully if he did?
Yes.
Would that make any difference to you?
Yes.
Why should any candidate be asked this question?
"Any" candidate shouldn't. But when for whatever reason the question arises during the normal course of a campaign (for instance, the publishing of a story from a source that has a record of being accurate on such stories) the question is very likely to be asked.
And when such a question is asked, the response potentially says something about whether the person "practices what they preach", and might tend to indicate whether the image they're projecting is phony or not.
Are there any limits to the admissions of a candidate’s past sins you would demand an answer to?
I suppose there are many practical limitations, but the question of fidelity does not fall within such limitations when contrary assertions are made, and the public wishes to know.
Of course, "none of your business" would be a possible answer, one that could carry its own obvious risks.
Do you believe in forgiveness?
Absolutely. Forgiveness, of course, usually comes after confession, assuming there is something to actually confess in the first place.
"If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness." - I John 1:9 (King James Version)
