Noonan: Obama Administration Suddenly Looks Like A House Of Cards.

But organization and money aren't the headline. The shift in mood and assumption is. The vote was a blow to the power and prestige not only of the unions but of the blue-state budgetary model, which for two generations has been: Public-employee unions with their manpower, money and clout, get what they want. If you move against them, you will be crushed.

Mr. Walker was not crushed. He was buoyed, winning by a solid seven points in a high-turnout race.

Governors and local leaders will now have help in controlling budgets. Down the road there will be fewer contracts in which you work for, say, 23 years for a city, then retire with full salary and free health care for the rest of your life—paid for by taxpayers who cannot afford such plans for themselves, and who sometimes have no pension at all. The big meaning of Wisconsin is that a public injustice is in the process of being righted because a public mood is changing.

People wonder about the implications for the presidential election. They'll wonder for five months, and then they'll know.

President Obama's problem now isn't what Wisconsin did, it's how he looks each day—careening around, always in flight, a superfluous figure. No one even looks to him for leadership now. He doesn't go to Wisconsin, where the fight is. He goes to Sarah Jessica Parker's place, where the money is.

There is, now, a house-of-cards feel about this administration.
