Early research into the new brain-wasting disease (which scientists suspect may be a variant of mad cow disease) indicates it only seems to to affect Republican politicians, striking first in the portion of the brain which causes most people to refrain from seeking gay sex with strangers in public restrooms.
Scientists have been quick to point out that autopsies of the brains of normal gay people (some of whom enjoy an occasional restroom liason) do not show the rotted appearance nor the unnatural hardening in the anti-choice lobe that appears to be a precursor of the disease.
