Union leaders have historically been Communists, so it isn't surprising that the Longshormen's union thinks Obamacare isn't liberal enough. Go through history and every Socialist/Communist movement was originally spawned by the UNIONS. They're the ones that organize the "spontaneous protests" and marches, they're the ones who make a big show for the media. Another reason the unions - at least the SEIU wants Obamacare is because they want the law to require that ALL healthcare employees be unionized. In some states, like Michigan, if you are providing in-home care for your own PARENTS and they pay you anything for your services, technically you are required to join a union. It's nonsense, but the unions and their Socialist politician supporters are determined to move this stuff forward.
