The issue is hypocrisy. This with the "do what it takes to win" campaign do not show Cruz to be the candidate he originally campaigned as.
Trump has had affairs and is on his third wife. He brags about having sex with his friends wives. Maybe you think his honesty is refreshing, but it certainly isn’t a high standard of moral behavior. If I am presumptuous in assuming you are a Trump supporter I apologize.
Trump has bedded hundreds of women, cheating on every wife he has ever had and you are making a pretense of caring whether a candidate has had an affair?
Give one shred of evidence that Cruz has had an affair. All you need is Trump’s own books to confirm his.
