The filibuster is far from the only delaying tactic available to Republicans as they try to hold off healthcare reform. Taegan Goddard glosses an article from Roll Call for us:
For instance, instead of offering a conventional amendment to the bill this week, Republicans used "an esoteric procedural tactic" that would send the bill back to committee with instructions to eliminate certain cuts. If successful, Republicans would force Democrats to "hold another filibuster-killing vote on whether to restart debate on the bill."
"Republicans said they are likely to use the procedural tactic repeatedly during debate this month as they seek to make the point that the Senate should go back to the drawing board on the health care bill."
This is going to be fun couple of months, isn't it?
