You missed the more important question
Don't care.
Look, I'm sorry bro, but while our eternal salvation and spiritual matters in general are ultimately the most important, political matters nonetheless count. Trump, for all of his silly character flaws, fought for the American founding more than any president since Reagan. That founding is under attack by the American Left, to establish a communo-fascist order.
Trump is a man who not only has a steel stomach for battle (he never tires of it, in fact he actually seems to feed off of it!), but he also has metallic gonads. No one has the cajones this man has, with maybe the exceptions of DeSantis or Cruz.
I do not know the Trump supporters you speak of. Of course, I do not personally know every Trump supporter, but the only ones who seem to fit the description you gave are the ones CNN and The NY Times show us. If those are your sources, then do NOT lecture me about your intellectual superiority.
And... let's say there are awful Trump supporters out there. There are awful people who claim to walk in the Name of Christ. Does that mean Jesus is unworthy?
Bottom line is, if the movement preserves and perpetuates the American founding principles, then it is worthy of your support. If you cannot see that, then I'd revisit that test of yours.
