The Republican party. Named for their regressive policies.
The Regressive party wants to bring us back to the stone age.
No, the other guy is wrong. The term regressive party may refer to something lame and boring like that, but it is also popularized by Maddox, and the one stance of the regressive party is that they are "Against Abortion, For Killing Babies."
The regressive party is awesome, because I've always hated babies and like to daydream about drowning them in puppy blood - maybe kitten blood, if no puppies are available.
