I'm going to quote the Rude Pundit in full on this one:
Technically, this is true. But all these articles fail to mention what the Miami Herald does distinctly note: "Only three members were on the floor and the bill's prime sponsor, Republican Sen. Mel Martinez of Florida, served as presiding officer."
And those three members proudly raised their voices, and yes, technically the bill passed unanimously, just as technically Terry Schiavo is still "alive."
Welcome to the circus.
