How can a spending bill originate in the Senate...?

Very easily:

Let's say HB1234 "The Waste Taxpayer Money Act" has passed the House and is awaiting action in the Senate.

The Senate can take HB1234 - amend it by gutting it completely and renaming it - pass it, and send it back to the House for consideration and a vote.

This happens pretty often - is legal - and gets around the "All spending bills must originate in the House" issue.

This happens at the state level also.

Um, that's not what the Constitution says: "All Bills for raising Revenue shall originate in the House of Representatives;" - these bills don't raise any revenue at all, they merely spend it.
