From the piece:
In the wake of its failed negotiations with the new Republican Congress that swept into power in the 2010 elections, the Obama administration learned some painful lessons. The main point of my long print story about this from October was that Obama had learned from his failures and was developing a plan to handle the negotiations that was going to surprise liberals and conservatives alike with its toughness. The first, and most important, piece of the strategy is using the expiration of the Bush tax cuts as a leverage point to isolate the GOP’s unpopular attachment to keeping tax cuts for the rich low. That goal seems well on its way to being accomplished. Now Obama is already moving on to the next piece — the debt ceiling.
