As symbolic gestures go, reading the constitution on the house floor falls in the "mostly harmless" category. Of course, the repubs skipped over some parts they decided were "irrelevant" because they didn't quite fit the agenda. So most every representative decided to skip the reading. Heck, new speaker John Boehner held a press conference right in the middle of the reading.
I'm glad that the 112th congress is starting on such a serious note.
