The creepy thing about John Boehner weeping so readily on a variety of subjects, is that the tears seem prompted by self-pity.
Boehner's labile behavior is troubling when you consider other historic wallowers in self-pity. Richard Nixon, who resigned the presidency after his plot to undermine the Constitution was uncovered; Adolf Hitler, inventor of industrial mass murder to effect genocide; and Jimmy Swaggart, evangelist who sinned. You can think of many more.
Self-pity is not pleasant to watch.
There are plenty of reasons to weep. Being wrapped up in yourself is not a good one to put on public display.
