This is what Pres. Benson said in 1977. He was secretary of Agriculture after WWII while a member of the Quorum of Twelve.
Another video that was inspiring.
This is the most I've ever heard politically from one of our church leaders. What is most interesting is that we are encouraged to vote our conscience. Since it was given as an address to BYU students at a devotional it isn't considered doctrine, but it sheds some light on his beliefs toward government and it's role in our lives. And he was a member of the government!
Mostly, I want to encourage those who are eligible to get out and vote.
