this one could be.
the clinton's stewardship of this nation's intelligence, defense, and justice apparatus - led directly to 9-11 just 7 months after they left office. for those 3000 americans, it was their "end of history".
give them another 8 years, and I can almost guarantee you that a WMD device of some kind will go off in a major US city. have that happen while the clintons are in the white house, and the Dems have congress - you may well see the Constitution suspended.
So what. Any liberal, of either party, is going to produce similar results. In fact, a "Republican" liberal tends to be able to forward the liberal agenda more easily. The proof? Look at Massachusetts. Could any Democrat, even in that liberal state, have pushed through gay marriage and socialized medicine like Mitt Romney has?
