Cruz gave an oath to support the nominee, and his failure to do so showed his lack of principles. His wining about alleged attacks on his wife and father shows it’s all about him, not what’s best for the country.
He made a promise to support, he didn’t take an oath to make an endorsement.
God, family, country - most conservatives’ and Christians’ order of allegiance. Cruz didn’t refuse to endorse because of all the malicious, hateful things said about him, but because of what was said about his wife and father. A man who won’t stand up for his family isn’t going to be much use to his country.
I think Cruz will support Trump’s policies and, hopefully, both of them will be successful in their work to preserve this Republic.
