Funny, when I said the same thing as you (living our values) you asked what did that have to do with anything.
But, be that as it may, you are still ignoring the fact that the world, in general, not just the USA, has become a post-Christian world. Christians are not in power in many places because of the hatred the world has for people with faith and convictions, not because of subservience. The balance of power needs to be restored in order for people with conviction can be voted into office. It can’t just be done because you say it should be done. IMO, though, the pendulum is starting to swing back, which gives hope, but until balance is restored, the best that most of us common people can do is what Christ commands us to do. Love God. Love other people. Make disciples. God’s timing is always perfect. He knows when the best time for things to happen is.
