The GOP are considering "re-branding" the Democratic Party as the "Democrat Socialist Party." Hilzoy provides the appropriate response, but in all honesty I'm not sure whether anything can be said in response to such total lunacy. I mean, official name-calling?
This reminds me of Tom's comment to my "Republicans are Irredeemably Evil" post. He was entirely right in theory that the Republican Party isn't irredeemably anything, but all the signs are that the party (under the watchful eyes of Rove, Cheney and, especially, Rush) are striking out in the exact opposite direction, into what Kevin Drum is calling "the ongoing intellectual collapse of the conservative movement". The intellectual and moral bankruptcy of so many of their leaders is so acute that I don't have any problems suggesting they themselves are irredeemable, and so the only way the GOP can recover is to cut them loose.
Thus far there isn't much sign of that. Which means one of two things. Either the Republican party will actually die (it's rare, but it happens), or at some point there will be insurrection and a massive U-turn, in which case the party will be redeemed, but only following such fundamental change that it would in many ways remain the same party in name only.
