President Obama has not been a do-nothing failure. He has some real accomplishments. He passed a health care expansion, a financial regulation expansion, stabilized the economy, started a national education reform initiative and has conducted a smart and tough war on Al Qaeda.

But there is another angle on the last two years: a president who won a sweeping political mandate, propelled by an energized youth movement and with control of both the House and the Senate — about as much power as any president could ever hope to muster in peacetime — was only able to pass an expansion of health care that is a suboptimal amalgam of tortured compromises that no one is certain will work or that we can afford (and doesn’t deal with the cost or quality problems), a limited stimulus that has not relieved unemployment or fixed our infrastructure, and a financial regulation bill that still needs to be interpreted by regulators because no one could agree on crucial provisions. Plus, Obama had to abandon an energy-climate bill altogether, and if the G.O.P. takes back the House, we may not have an energy bill until 2013.

Obama probably did the best he could do, and that’s the point. The best our current two parties can produce today — in the wake of the worst existential crisis in our economy and environment in a century — is suboptimal, even when one party had a huge majority. Suboptimal is O.K. for ordinary times, but these are not ordinary times. We need to stop waiting for Superman and start building a superconsensus to do the superhard stuff we must do now. Pretty good is not even close to good enough today.
