Apologies if this has been posted; did a search and did not find it. From the Feb 22, 2010 edition of The Nation -- I believe it sums up the feelings of many progressive voters very well:
How to Get Our Democracy Back

We should remember what it felt like one year ago, as the ability to recall it emotionally will pass and it is an emotional memory as much as anything else. It was a moment rare in a democracy's history. The feeling was palpable--to supporters and opponents alike--that something important had happened. America had elected, the young candidate promised, a transformational president. And wrapped in a campaign that had produced the biggest influx of new voters and small-dollar contributions in a generation, the claim seemed credible, almost intoxicating, and just in time.
