I never thought a president would be impeached in my lifetime, but Clinton was (and should have been). I never thought a president would be elected again without winning the popular vote, but Bush was (and legitimately so). I never thought the continental United States could be struck as it was on September 11, 2001. I have to say — at least at this point — that I don’t believe it is impossible for the Republican nomination to be settled at the convention. I’m not saying it will, but it can’t be completely ruled out.
