John Kennedy actually said...

Dear Mr.____________:The election of the President of the United States is the supreme expression of the free choice of the American people.

As one who participated in a presidential campaign, I heartily endorse this recommendation.

By our free choice, we vote and in other ways participate in the politics of our democracy.

For the citizens' free choice to be exercised meaningfully, they must be well-informed about opposing candidates, parties and issues.
