I recall an abortion protest during the last democratic convention (iirc) where the protester (randall terry, perhaps?) was holding an apparently aborted baby. it was unsettling, but effective. then the video crew cut over to the headquarters of some anti-life organization, and caught the palpable relief in the crowded room when it was reported that the baby was stillborn, not aborted. (which stood to reason, really, since it looked completely intact.)
but I have always thought they were missing the point in a big way.
on edit : it may have been the 2000 dem convention, now that I think about it.
