Tax credit extension standstill?!

I just read an article that congress has not passed the tax credit extension!!! What are they waiting for? There are roughly 4,300 New Jersey buyers that will lose out on the tax credit if they don't extend it. And it's all because their sales were postponed or short sales haven't been approved. This should be an easy decision and it's taking so long! What are your thoughts? Should they pass the extension?
