NOTE: This is probably a hoax. I'm relieved to hear that.
If this invitation to a Republican party, from a diary on Daily Kos is true, it reveals a lot about the inner Freudian of some Republicans:
A Message From Your Host
We will have a Jesse Jackson piñata , a dunk tank where you'll get the chance to sink my wife who will be dressed as Hilary Clinton, and a special guest appearance by my uncle - Rep. Timothy V. Johnson who will be giving away "Proud to be G.O.P." American Flag windbreakers. Bring a side dish if you like. We will have burgers, hot dogs, chili, and pizza, but nothing vegetarian! This party is family friendly, so feel free to bring children. It's never too early to get them involved!
See how there are flags, family values and the rituals of pretending to murder a black man and an uppity woman who also happens to be some wingnut's wife? And children should be introduced to this as early as possible! I feel a little sick, so I hope that it is a joke, even if a poor one.
Added later: The party invitation on the gop.com excludes the reference to beating a black man but still promises the drowning of Hillary Clinton. Which reminds me of a long-overdue post about how racism is still not quite mainstream but sexism has arrived, pretty much. And yes, I know that they are pretending to drown an individual woman but boy, does Hillary not stand for all that the wingnuts don't like in women!
