I for one would not be too surprised to see Cheney step aside, citing perhaps "health reasons", but obviously accomplished mainly to give political advantage to a 2008 presidential hopefull, which he of course is not. It would be a masterful political stroke for the GOP.

However, before anyone waxes too enthusiastically over the possibility of resignation, I would remind y'all that (IMO) Mr. C, undeniably the most influential sitting VP in at least the last 100 years, will continue to call the shots in this administration either way, with or without a title, just as he has done all along.
