Many motorcyclists (and I ride one) cover their helmets with stickers. My helmets have once small sticker on the back.
It states:
I am not a Democrat. I am not a Republican. I am an American. There is a difference.
I don’t believe in political parties and have never belonged to one although I did work in politics once and worked at one point or another for either.
I’m not a conservative or a liberal.
I’m an American.
Just that.
Nothing else.
