I think it's appropriate now for liberals to begin our "I Told You So" list. Conservatives are very good at this, as we've seen (e.g. underpants bomber), and this is one thing liberals should emulate. When Democrats get voted out of office in 2010 because unemployment is too high, clearly the correct response is "I Told You So." When climate change makes the world less livable and less stable, clearly the correct response is "I Told You So." Feel free to make up your own "I Told You So" scenarios.
What's really frustrating is that in a few months we just know this whole frustrating cycle will be repeated: Democrats will do nothing and their do-nothingism will somehow indict liberalism rather than, say, do-nothingism. Democrats never miss an opportunity to miss an opportunity.
