Daniel Henniger: The Fall of the House of Kennedy

Scott Brown's victory in Massachusetts will not endure unless Republicans clearly understand the meaning of "the machine" that he ran against and defeated.

Yes, it is about a general revulsion at government spending, what is sometimes called "the blob." But blobs are shapeless things, and in the days ahead we will see the Obama White House work hard to reshape the blob into a deficit hawk. Unless the facade is ripped away, the machine will survive....

The central battle in our time is over political primacy. It is a competition between the public sector and the private sector over who defines the work and the institutions that make a nation thrive and grow.

In 1962, President John F. Kennedy planted the seeds that grew the modern Democratic Party. That year, JFK signed executive order 10988 allowing the unionization of the federal work force. This changed everything in the American political system. Kennedy's order swung open the door for the inexorable rise of a unionized public work force in many states and cities....

The states in the North and on the coasts turned blue because blue is the color of the public-sector unions. This tax-and-spend milieu became the training ground for their politicians....

There's no way out for these Democrats. They made a Faustian bargain 40 years ago with the public unions. For the outlays alone, they'll get some version of the Obama health-care bill. They'll also go to the same old "populist anger" well.

Scott Brown's victory has given the GOP a rare, narrow chance to align itself with an electorate that understands its anger. Now the GOP has to find a way to disconnect from a political legacy that smothered governments at all levels and is now smothering the Democratic Party.
