Bigfoot for President 2012 is the first I have seen for the 2012 campaign. I will try to document new ones as I see them here.
A few quotes from the site:
"Political veiws, not a Democrat, and not a Republican, I belong to a brand new party, called: Do the right thing, Or I'll take your but, Out to the woodshed, and kick it."
"America deserve's better, than you, Democrat and Republican's!!!"
"Well thank-you, for reading about me, I really care, about this great nation, and all of it's inhabitant's. That's why I, Bigfoot am running for President in 2012."
"And yes Abraham Lincoln, was actually, a clean shaven sasquatch."
