Carl Truman wrote: After all, an evangelicalism that finds voting for Trump (or Biden) to be a moral imperative for all, and a Catholic hierarchy that allows Biden to oppose with impunity so many of its cherished teachings, would not seem to be particularly pungent in their Christian distinctiveness. Is such “Christianity” merely secularism in a religious key? 
No, Christianity is not merely secularism in a religious key in America. Though there were moments of confusion, and excesses, like all countries have, but American religious input in politics is probably one of the last bastions in God’s sizable footprint in its social economic life and expressed valiantly in politics. Different from European politics, where religion is so far away from politics, understandably how folks with an European background may feel in this. But America must continue to keep her religious fervor for some very good reasons, example, for the protection of the unborn and religious liberty, and when I say religious, I mean the spiritual life of millions of evangelical Christians, including the Catholics. No matter how superficial they may look in the two presidential candidates in their spiritual life, the God ordained spiritual religious values must be preserved in the whole land where folks say “In God we trust”, and “God bless America”, a voice of such is fast fading out in many parts of the world. Admittedly, our presidential candidates are far from ideal, guess when was the last time we had one? In the US or any country in the world? But don’t throw out or surrender the little that we have.
Even as we speak now, Justice Amy Barrett has just been confirmed tonight as the newest Supreme Court justice, a woman of solid conservative constitutions originalist, faithful as a charismatic Catholic, you can’t ask for more. Apparently, she is the most impressive SCOTUS candidate the senate has seen, voiced by many of the Republican senators. How did that happen? That happened because we have a president that pushed for godly conservative originalist justice, and he’s kept his words. It does make a huge difference! Actions speak louder than words!
The protection of the unborn will go to the Supreme court very soon, and the time has come for God to ordain his acts to save any more killing of the unborn. Religious liberty is facing a constant assault from the left wing politicians, academia, liberal, and progressive, and Biden even advocated for a 7 years old the choice to have his or her sex changed. Transgenderize to a level that makes even a liberal shake. That’s what we have to deal with today.
Where is God in all these? God is watching over us and making his next move. Don’t ever forget the doctrine of Providence, i.e. God provides and watch over us. He protects us. It may not seem to be understandable why God let this Roe V Wade passed many years ago resulted in thousands and thousands unborn baby death, we will have to put our trust in our sovereign big God. In fact, He has watched over us and protected in so many things in our lives, in our nation. Look around, and give praise to our God. When David was down, he questioned God, but he turned around exulting in God’s faithfulness and his steadfast love. We must put our faith in God.
Finally, the whole question is whether we should have Christian politicians that profess the name of our God into election? Of course, we want that, however dented it may be. For Biden, it’s not only dented, it’s all crooked. For Trump, his personal characters fall short substantially of his narcissistic and self-egoist character, plus his infidelity and past 3 marriages past. But you know, he put in the most conservative supreme court judges and changed the nation. He defended religious liberty from the onslaught of the sexuality transgenderism onslaught, etc. Bottom ,line, his actions are far better than his bombastic character and the flaws and sinful life of the past. I think we can eat that, and continue to praise God.
I also recommend Al Mohler’s article where many of my thoughts are in agreement with. https://albertmohler.com/2020/10/26/christians-conscience-and-the-looming-2020-election
Al Mohler puts it beautifully and convincingly: “Let me be as clear as I know possible: President Trump’s behavior on Twitter and his divisive comments and sub-presidential behavior are an embarrassment to me. Constantly. His arrogance and ego and constant need for adulation drive me to distraction. But character is some strange combination of the personal, the principled, and the practical. Let me put it another way—I cannot accept the argument that a calm man who affirms the dismembering of babies in the womb has a superior character to a man who rants like Genghis Khan but acts to preserve that life. In my ideal world, I would vote for a candidate in whom the personal, the principled, and the practical earn my admiration. I do not live in that world. I live in this world, and I must act accordingly.” 
Go and Vote Wisely America. God bless America.
