Palin indeed was wearing an ear piece in her right ear. Watch the video again on a PC or a high definition TV. The piece that's actually in her ear
is clear but you can see a white clip that attaches it to her glasses. I waited until I saw the left side or her glasses five or six times to be
certain that it wasn't a part of the frame and waiting for other people in the room to ask the question, "Is there something in her ear or on her
glasses".
Everyone was able to point to it. Guys at work are talking about it too.
Mod edit: Fixed all-caps in title.
UPDATE
THIS POST appears to disprove the earpiece observations.
Still capture from HD DVR replay of debate...
