Human Events Explains it..
The following four-step scenario describes one way liberals plan to work the rules in their favor to get Obamacare through the Senate:
Step 1: The Senate Finance Committee must first approve the marked-up version of Sen. Max Baucus’ (D.-Mont.) conceptual framework. Then Senate Majority Leader Harry Reid (D.-Nev.) can say that two Senate Committees have passed a health care bill, which will allow him to take extraordinary steps to get the bill on the Senate floor.
Step 2: Sen. Reid will take the final product of the Senate Finance Committee and merge it with the product of the Senate Health, Education, Labor and Pensions (HELP) Committee, which passed on a party-line vote in July.
Step 3: Now, Obamacare will be ready to hitch a ride on an unrelated bill from the House. Sen. Reid will move to proceed to H.R. 1586, a bill to impose a tax on bonuses received by certain TARP recipients.
The move to proceed needs 60 votes to start debate. After the motion is approved, Sen. Reid will offer Obamacare as a complete substitute to the unrelated House-passed bill. This means that the entire healthcare reform effort will be included as an amendment to a TARP bill that has been collecting dust in the Senate for months.
Step 4: For this strategy to work, the proponents would need to hold together the liberal caucus of 58 Democrats (including Paul Kirk who was named last Thursday to replace Sen. Kennedy), and the two Independent senators (Joe Lieberman of Connecticut and Bernie Sanders of Vermont). These members will have to all hold hands and vote against any filibuster. Once the Senate takes up the bill, only a simple majority of members will be needed for passage.
Once the Senate passes a bill and sends it to the House, all the House would have to do is pass the bill without changes and President Obama will be presented with his health care reform measure.
