The office of the Presidency has been without facial hair for far too long. A President that has facial hair indicates several things.
It would promote facial hair growth in the professional workplace, giving thousands of men the courage to express themselves facially.
Having facial hair fosters a sense of stability and integrity. A leader of the free world needs all the help he can get. Why not use this as a device in a way not dissimilar to the infamous "flag pin?"
In effect, you will be representing a group of people often left without advocates in Washington, despite their numbers in society.
Some of the greatest Presidents and leaders of our country have wielded facial hair! Always remember, with great beard, comes great responsibility.
