Why the Obama Era only lasted two years

Plutocracy Now: What Wisconsin Is Really About

[...] Still, one striking fact remains: Liberal reform is not a continuous movement powered by mere enthusiasm. Reform eras last only a short time and require extraordinarily intense levels of cultural and political energy to get started. And they require two other things to get started: a Democratic president and a Democratic Congress.

In 2008, fully four decades after our last burst of liberal change, we got that again. But instead of five or six tumultuous years, the surge of liberalism that started in 2008 lasted scarcely 18 months and produced only two legislative changes really worthy of note: health care reform and the repeal of Don't Ask, Don't Tell. By the summer of 2010 liberals were dispirited, political energy had been co-opted almost entirely by the tea party movement, and in November, Republicans won a crushing victory.

Why? The answer, I think, is that there simply wasn't an institutional base big enough to insist on the kinds of political choices that would have kept the momentum of 2008 alive. [...]

This is, of course, pie in the sky. Organized labor has become a shell of its former self, and the working class doesn't have any institutional muscle in Washington. As a result, the Democratic Party no longer has much real connection to moderate-income voters. And that's hurt nearly everyone.

Disheartening to be sure.
