The rise of the Tea Parties has provoked scorn and concern among the political elite, as some dismiss the movement's influence over our politics while others warn of the dangers of demagoguery. But America's brand of populism — so different from the rest of the world's — has often enriched, not harmed, our politics; it has also led to some enduring political coalitions. Can today's Tea Partiers do the same? Only if they heed the lessons of the unique history of American populism.

The past two years have offered a real-world test of some key assumptions behind Keynesian fiscal policy, and the results have not been encouraging. Yet even as their stimulus package has failed to keep unemployment in check, President Obama's economic advisors insist that their models were right, and that what we need now is more of the same. Their experience in this challenging time offers a stark reminder that economists should always be guided by rigorous empiricism — and a healthy dose of humility.

Government measures of unemployment are as widely interpreted, and as frequently misinterpreted, as modern art. So what exactly does the "unemployment rate" measure? And are politicians — on both the right and left — wise to use other so-called "real unemployment" figures to push their pet economic policies?

From taking over General Motors to fixing executive compensation on Wall Street, recent government interventions in the economy have been profound and unprecedented. But are they constitutional? Ever since the New Deal Court stripped economic liberty out of our understanding of the Constitution — especially of the 14th Amendment — that question has become harder to answer. Now more than ever, Americans need a better grasp of the proper place of economic liberty in our constitutional order.

President Obama's expansion of the government service state — at the expense of local, more traditional community associations — is the latest manifestation of a longstanding Progressive ideal. But it is also likely to carve fault lines into the Democratic base. Can conservatives win over those disaffected by Obama's efforts, as they have in past moments of liberal overreach? Perhaps — but only by opening conservatism to new and unexpected sources of wisdom on the question of community.

Amid a new kind of war and unprecedented breaches of national security, Americans' views of executive secrecy are still shaped by an incident that took place four decades ago: Daniel Ellsberg's leak of the Pentagon Papers. In the years since the infamous disclosure, however, our understanding of the episode has devolved into caricature. The truth of the case, and its real legal consequences and moral meaning, are far more complex — and more interesting.

The Patient Protection and Affordable Care Act will entrench and exacerbate, not eliminate, the worst failings of American health care. If any genuine, effective reform of our health-care system is to occur, Obamacare must first be repealed. But what should pro-market reformers advocate in its place? A series of discrete, market-oriented measures to reduce costs, reform our health-care entitlements, and put doctors and patients in the driver's seat.
JAMES C. CAPRETTA and TOM MILLER
Champions of the health-care legislation enacted this spring point to the law's coverage of Americans with pre-existing medical conditions as one of its chief benefits. But unfortunately, the law throws the baby out with the bathwater — overturning our entire health-care system in order to address a relatively narrow problem, and in the process only worsening other difficulties. A system of state-run high-risk insurance pools would do a much better job of solving the "pre-existing condition problem" — while also preserving and strengthening what does work about American health care.
JOHN HOOD
Rather than fixing Medicaid — the deeply flawed and immensely expensive program of health coverage for the poor — Obamacare vastly expands the program, and puts it at the very heart of American health care. Any serious effort to control health-care costs and get America's public finances in order must therefore begin by rolling back Obamacare and transforming Medicaid.
