The President's FIRST duty is to uphold the rule of law and the Constitution of the United States. That comes before nominating pro-life justices, or cutting taxes, or supporting Israel, etc. Unless you have been looking at him through Fox-colored glasses, I think the answer concerning Trump is overwhelmingly NO. It was bad enough that many Christian leaders supported him at election time, but I think I can understand it up to a point. At that time there was the contrast with Hillary. With respect to his extramarital relationships, I think we have the right to ask him to just come clean, and either tell the country that he doesn't think he has a duty to be a faithful husband because he has considers that requirement to be an outdated religiously-based prudish moral rule, or to say that he is deeply repentant for the disrespect for marriage, in word and deed, that he has shown in the past and that he has amended his behavior in the meantime. This is especially true for Christians who look to a Republican President to support traditional marriage and who find same-sex marriage to be a treat to that institution. Don't such Christians have a right to know if the President they are supporting respects the institution of marriage as they understand it? And shouldn't such Christians demand such answers from the President they support?
Someone willing to make a payment of amount a few times my annual salary to keep someone silent is someone who is liable to be blackmailed by a foreign government to keep other improprieties quiet. His ability to put the American people first and uphold the Constitution has to therefore be questioned.
Evangelical leaders are getting up on TV and giving Trump a whole bunch of breaks that they wouldn't give Clinton or any other previous President. Worse yet they focus on the actual affair, when the attempt, in violation of campaign finance laws, to keep someone from talking about the affair is far more serious. And if he has people out making threats of physical violence, this is worse.
I am tired of hearing that the public policy bottom line is all that matters. A President who can't uphold the rule of law, who is so compromised that we can expect nothing but scandal after scandal, is someone who the American people will sooner or later turn against. I liked a lot of John Edwards' public policy proposals. But his character was so compromised that I would be far more comfortable with Mitt Romney in the White House than him. I think those who voted for Trump should have seen the handwriting on the wall when they voted for him back in 2016, but this constant talk of "mulligans" and "we believe in forgiveness" is nauseating and with a lot of people yes, it damages the credibility of Christianity. The Franklin Grahams and Tony Perkinses, not to mention Paula White, who says its a sin to oppose our President since God raises up kings, (How come we didn't hear that when Obama was in office), yes, they do give opponents of Christianity ammunition.
