Carter has done some serious damage and continues to try to cause this country even more, but after the time that has passed, we can, at least, judge the amount and kind he's responsible for. Clinton, we can't even guess how much damage and what kind, since the time interval is too short. If this open borders-illegal amnesty move of Bush's becomes law, he may singlehandedly finish us off before we even know how damaging Clinton was.
Clinton & Carter sold out our country both politically & militarily. But Clinton also egregiously debased our nation morally.
BTW, Bush is only guilty in one of these areas, so claims that he’s the worst President, ever, are way off base.
