Voting is an important part of living in a democracy. So "Vote to show God is real."
You might well ask, "Just how does my voting show that God is for real?" For guidance, look to the values expressed in the holy scriptures and saints of your particular faith.

In our times, voting as an act of love, true love, confidence that shows that God is real.
Avoid pulling the lever those shouting "fake news" at reputable journalists, seeking white supremacy, building walls, moats and minefields justified by make-believe fears. Fear campaigns are old political techniques to hijack democracy, copies of Hitler in Germany and Mussolini in Italy in the previous century.
Look to history and learn how democracies in Europe were hijacked in the 1930s. Start here: watch "Rick Steves: The Story of Fascism in Europe," produced 2018. Perhaps the best available 60-minute recap of the campaigns for fascism.
