Where was all this concern about giving the minority a voice in government three years ago?

Remember what happened then? Sure you do... the Republicans were maneuvering to eliminate the filibuster, and remove the "voice in government" for the other side.

Show of hands please - who objected then?

I am sure the Republicans will be true to their principal and not use the filibuster now.

Yeah, right. In the last session, they set the record for the most filibusters ever in the history of the USA.
