In the spirit of 'doing'…
Here is something that we all can do every day, every time and it should make a serious difference.
Our political problems are symptoms of a culture problem. In our culture, bearing false witness, deceit, good ole fashioned telling lies is celebrated. Anyone remember in the old west movies, calling someone a lair or a cheat was the quickest way to get shot? We don't do that anymore. Why?
People proudly proclaim how well they can lie these days. No one calls anyone out on it anymore. No one calls out a liar anymore. There isn't any negative consequences for lies.
Stop that.
If you're a boss, fire the liar on the spot. Stop tolerating this bad behavior. Make it hurt to lie to someone. This will help change the culture back to something that won't condone and pardon voter fraud.
