Okay since you two guys insist, I'll try to answer.
Why do Evangelicals support someone who is a serial adulterer, been married and divorced few times, made fun of Christians, don't believe in Christian values, is greedy and so on?
Is that the way the Evangelicals want to spread the Gospel of Jesus Christ? Apparently those Evangelicals (not all of them mind you), do not understand how to represent Jesus Christ and his message.
I've already answered your question. Policies. Policies for the betterment of the country. Stopping illegal immigration. Becoming energy self sufficient. Relaxing stupid industrial restrictions (especially on small businesses), just to name a few. Ever hear God and Country (not the song, but the inspired saying)? We (1) believe in God and (2) we love our country and constitutionality. Some of us feel Trump would continue our founder's wishes better than Biden, just as we did with Hillary.
Most religions basically put it out and say we believe this, you should too. But that's as far as it goes, take it or leave it. First Amendment, right? No protests in the streets, none of that shit.
I grew up in a small church (about 180 members). Aside from tithes, we held public dinners, some free, some to raise money to send kids to camp and bake sales. We advertised, everyone does.
If you come to a church, you are free to come and go as you please. But if you stay, you should expect at least a 5 minute sermon. We also hold public gatherings, but so does the City Band.
That is how we spread the Gospel. We know how to represent ourselves, but some of us admittedly stray occasionally. Are you perfect?
But for the record, I do not think much at all of those preachers who lead lavish lifestyles.
