McCain may be more bitter about losing to Bush in 2000 than to Obama in 2008.
Anyway, I guess the question now is to find a losing candidate who wasn't bitter.
Maybe somebody who never expected to win: John W. Davis or Alton E. Parker.
Mitt Romney doesn’t seem particularly bitter, he’s very cocksure that he’ll be President eventually. That prophecy thing, no doubt. He/s gonna ride in on a white horse and save the Constitution, lol, thinly veiled leftist that he is.
Cruz showed his @ pretty good too, come to think of it, all that wild behavior leading up to and during the Republican convention, that infantile stompy-feet speech refusing to endorse Trump and all. I can’t believe all the FReepers who give him a pass on that.
