To the corrupt class, it only matters that the bill number originated in the House. They make the rules.
I have found a potential problem with making a challenge under this clause of the Constitution. In prior cases, the Supreme Court already watered down this Consitutional requirement, called the “Origination Clause”:
A statute which raises funds to support a particular program, as opposed to raising revenue for the general Treasury, is not considered a bill for raising revenue within the meaning of the Origination Clause. United States v. MunozFlores, 495 U.S. 385, 398 (1990).
Only if it could be shown Obamacare penalties are not used to pay for this program would this challenge appear to have a chance of success.
What about the "germaneness" of the amendment to the intent of the original bill. Isn't that a rule?
