From the piece:
ABC’s Jonathan Karl heard from two senior Republican lawmakers that the most likely fallback plan is for House leadership to bring up the middle income Bush tax cuts for a vote later this month. A leadership aide told Karl the plan is under consideration but that no decisions have been made.
Here’s how it would work.
The bill would come to the floor, and Republicans would vote ‘present’ to register their disapproval with letting the top marginal rates go up, allowing Democratic votes to carry it to passage. Having already cleared the Senate, the bill would be sent to the White House and signed into law. Over and done, middle class tax increases averted.
