WASHINGTON – The magnificent turmoil now gripping statehouses in Wisconsin, Ohio, Indiana and soon others marks an epic political moment. The nation faces a fiscal crisis of historic proportions and, remarkably, our muddled, gridlocked, allegedly broken politics have yielded singular clarity.

At the federal level, President Obama’s budget makes clear that Democrats are determined to do nothing about the debt crisis, while House Republicans have announced that beyond their proposed cuts in discretionary spending, their April budget will actually propose real entitlement reform. Simultaneously, in Wisconsin and other states, Republican governors are taking on unsustainable, fiscally ruinous pension and health care obligations, while Democrats are full-throated in support of the public-employee unions crying, “Hell no.”

A choice, not an echo: Democrats desperately defending the status quo; Republicans charging the barricades.

Wisconsin is the epicenter. It began with economic issues. When Gov. Scott Walker proposed that state workers contribute more to their pension and health care benefits, he started a revolution. Teachers called in sick. Schools closed. Demonstrators massed at the capitol. Democratic senators fled the state to paralyze the Legislature.

Unfortunately for them, that telegenic faux-Cairo scene drew national attention to the dispute – and to the sweetheart deals the public-sector unions had negotiated for themselves for years. They were contributing a fifth of a penny on a dollar of wages to their pensions and one-fourth what private-sector workers pay for health insurance.

The unions quickly understood that the more than 85 percent of Wisconsin not part of this privileged special-interest group would not take kindly to “public servants” resisting adjustments that still leave them paying less for benefits than private-sector workers. They immediately capitulated and claimed they were only protesting the other part of the bill, the part about collective bargaining rights.

Indeed. Walker understands that a one-time giveback means little. The state’s financial straits – a $3.6 billion budget shortfall over the next two years – did not come out of nowhere. They came largely from a half-century power imbalance between the unions and the politicians with whom they collectively bargain.

In the private sector, the capitalist knows that when he negotiates with the union, if he gives away the store, he loses his shirt. In the public sector, the politicians who approve any deal have none of their own money at stake. On the contrary, the more favorably they dispose of union demands, the more likely they are to be the beneficiary of union largesse in the next election. It’s the perfect cozy setup.

To redress these perverse incentives that benefit both negotiating parties at the expense of the taxpayer, Walker’s bill would restrict future government-union negotiations to wages only. Excluded from negotiations would be benefits, the more easily hidden sweeteners that come due long after the politicians who negotiated them are gone. The bill would also require that unions be recertified every year and that dues be voluntary.

Recognizing this threat to union power, the Democratic Party is pouring money and fury into the fight. Private unions have shrunk to less than 7 percent of the working population. The Democrats’ strength lies in government workers who now constitute a majority of union members and provide massive support to the party. For them, Wisconsin represents a dangerous contagion.

Hence the import of the current moment – its blinding clarity. Here stand the Democrats, avatars of reactionary liberalism, desperately trying to hang on to the gains of their glory years – from unsustainable federal entitlements for the elderly enacted when life expectancy was 62 to the massive promissory notes issued to government unions when state coffers were full and no one was looking.

Obama’s Democrats have become the party of no. Real cuts to the federal budget? No. Entitlement reform? No. Tax reform? No. Breaking the corrupt and fiscally unsustainable symbiosis between public-sector unions and state governments? Hell no.

We have heard everyone – from Obama’s own debt commission to the chairman of the Joint Chiefs of Staff – call the looming debt a mortal threat to the nation. We have watched Greece self-immolate. We can see the future. The only question has been: When will the country finally rouse itself?

Amazingly, the answer is: now. Led by famously progressive Wisconsin – Scott Walker at the state level and Budget Committee Chairman Paul Ryan at the congressional level – a new generation of Republicans has looked at the debt and is crossing the Rubicon. Recklessly principled, they are putting the question to the nation: Are we a serious people?
