Given a choice between evil and smart or good and stupid, I'll choose good and stupid every time.
I would even go so far as to say that it is not possible for a party to be good and smart. If a party is good and smart, it will completely destroy the rival party and assume absolute power. Given absolute power, it is only a matter of time before it becomes evil and smart and all-powerful as well.
The Stupid Party... Wear the badge with pride...
"So, Lone Star, now you will see that evil will always triumph, because good is dumb."
