Noonan: Tea Party thrives because it promotes decentralization while the GOP, like the Democrats, brings more government

This fact marks our political age: The pendulum is swinging faster and in shorter arcs than it ever has in our lifetimes. Few foresaw the earthquake of 2008 in 2006. No board-certified political professional predicted, on Election Day 2008, what happened in 2009-10 (New Jersey, Virginia and Massachusetts) and has been happening, and will happen, since then. It all moves so quickly now, it all turns on a dime.

But at this moment we are witnessing a shift that will likely have some enduring political impact. Another way of saying that: The past few years, a lot of people in politics have wondered about the possibility of a third party. Would it be possible to organize one? While they were wondering, a virtual third party was being born. And nobody organized it.

Here is Jonathan Rauch in National Journal on the tea party's innovative, broad-based network: "In the expansive dominion of the Tea Party Patriots, which extends to thousands of local groups and literally countless activists," there is no chain of command, no hierarchy. Individuals "move the movement." Popular issues gain traction and are emphasized, unpopular ones die. "In American politics, radical decentralization has never been tried on such a large scale." Here are pollsters Scott Rasmussen and Doug Schoen in the Washington Examiner: "The Tea Party has become one of the most powerful and extraordinary movements in American political history." "It is as popular as both the Democratic and Republican parties." "Over half of the electorate now say they favor the Tea Party movement, around 35 percent say they support the movement, 20 to 25 percent self-identify as members of the movement."

So far, the tea party is not a wing of the GOP but a critique of it. This was demonstrated in spectacular fashion when GOP operatives dismissed tea party-backed Christine O'Donnell in Delaware. The Republican establishment is "the reason we even have the Tea Party movement," shot back columnist and tea party enthusiast Andrea Tantaros in the New York Daily News. It was the Bush administration that "ran up deficits" and gave us "open borders" and "Medicare Part D and busted budgets."

Everyone has an explanation for the tea party that is actually not an explanation but a description. They're "angry." They're "antiestablishment," "populist," "anti-elite." All to varying degrees true. But as a network television executive said this week, "They should be fed up. Our institutions have failed."

I see two central reasons for the tea party's rise. The first is the yardstick, and the second is the clock. First, the yardstick. Imagine that over at the 36-inch end you've got pure liberal thinking—more and larger government programs, a bigger government that costs more in the many ways that cost can be calculated. Over at the other end you've got conservative thinking—a government that is growing smaller and less demanding and is less expensive. You assume that when the two major parties are negotiating bills in Washington, they sort of lay down the yardstick and begin negotiations at the 18-inch line. Each party pulls in the direction it wants, and the dominant party moves the government a few inches in their direction.

But if you look at the past half century or so you have to think: How come even when Republicans are in charge, even when they're dominant, government has always gotten larger and more expensive? It's always grown! It's as if something inexorable in our political reality—with those who think in liberal terms dominating the establishment, the media, the academy—has always tilted the starting point in negotiations away from 18 inches, and always toward liberalism, toward the 36-inch point.
