Libertarians need to hear:

Let us never forget that government is ourselves and not an alien power over us. The ultimate rulers of our democracy are not a President and senators and congressmen and government officials, but the voters of this country.

~ Franklin D. Roosevelt

Democrats need to hear:

Nobody will ever deprive the American people of the right to vote except the American people themselves and the only way they could do this is by not voting.

~ Franklin D. Roosevelt
