The debate over whether the unborn are citizens of the United States is another way of justifying Roe vs Wade. Our founding documents, including the DOI, states that "we are endowed by our Creator with certain inalienable rights, among them are life, liberty, and the pursuit of happiness." Abortion and those who support it is an affront and violation of our most basic principles as a nation.
We are not a theocracy. We are a Constitutional democratic-republic. Christ told Pilate that he would have no power except that it came from above. Whoever is in office was put there by the Lord for His purposes. Another element is that we are commanded by the Lord to obey the laws of our land.
Another mistake I always see in posts is, you are not voting for Trump or Clinton. You are voting for electors pledged to those candidates. So if you are going to worry about the Christian character of someone, maybe you should examine that of the electors you are voting for, to see if they are honest enough to vote for their pledge. Render unto Caesar. Which candidate will govern better by the Constitution? That is the question. The federal governments job by the Constitution is to protect us. Every program Hillary harps on, free college, global warming, going to war without a decoration of war, increased government, free borders, etc. not a one is mentioned in the Constitution.
Are you going to put your trust in a person who has committed treason, perjury, theft, and probably murder, or someone who curses and some women who say he groped them decades ago? (Gee it did not bother me for 30 years, now it does) When Trump makes deals under the table it is with his money, when Hillary did it, it was with my money. It does not take a lot of brains to figure out who to vote for.
