I donโ€™t remember a more vivid case of tricky legislating than the attempt to shove Obamacare down the collective throat. And hereโ€™s the latest example. The Senate version of Obamacare is actually an unrelated House Bill that has already passed the Lower Chamber. From the Bill:

To amend the Internal Revenue Code of 1986 to modify the first-time homebuyers credit in the case of members of the Armed Forces and certain other Federal employees, and for other purposesโ€ฆAMENDMENT IN THE NATURE OF A SUBSTITUTE intended to be proposed by Mr. REID (for himself, Mr. BAUCUS, Mr. DODD, and Mr. HARKIN) Viz: Strike all after the enacting clause and insert the following [2076 pages]

Why do this? By gutting the passed bill and substituting the Obamacare plan, it could avoid the necessity for a conference committee. If the bill passed, it would go back to the House, and if it passed without amendment, there would be no need for a conference committee. Itโ€™s a vehicle to allow a fast track to passage.
