Often in politics one moment sets up another. For example, the violence, disorder, and campus unrest in 1967-1968 opened the way for Richard Nixon’s first presidential win. Watergate created the conditions that allowed Jimmy Carter to emerge victorious in 1976. Mr. Carter’s incompetence led to Ronald Reagan’s landslide victory in 1980. George W. Bush prevailed in 2000 by offering a contrast to Newt Gingrich, who by then was viewed as polarizing and unpopular. And the difficulties in Iraq helped Barack Obama win the presidency in 2008.

Something similar may be taking place with ObamaCare.

The Affordable Care Act is the personification of liberalism in terms of its centralization of power, its coercive elements, its nearly unlimited faith in technocratic solutions, and its absolute confidence that the effects of a massive restructuring of our health-care system could be controlled.

The multiple and multiplying failures of ObamaCare may well lead to a more widespread appreciation for certain conservative truths, including the virtues of limited government, the law of unintended consequences, and the fact that change can often lead to disruption. Juxtaposing the glorious things the president said the Affordable Care Act would achieve with its mounting problems is a useful reminder that the world is enormously complicated and the ability of government to carefully order and arrange the pieces of that world is really quite limited.

The Obama presidency, before it’s through, will likely cause the American people to be a bit more dubious about the next person who comes along and promises to heal the planet, remake the world, and slow the rise of the oceans; who campaigns on incantations and inspires a cult of personality; and who believes his mere touch is enough to transform things for the better. The Obama presidency may also deepen the public’s appreciation for prudent reforms, actual achievements and what George Will once called (in referring to former Indiana Governor Mitch Daniels) the “charisma of competence.”

Barack Obama is the avatar of progressivism. His failure, and most especially the failure of his signature domestic achievement, is producing a legacy of disillusionment and damaged lives. Americans will look to an alternative. Which means a new conservative moment awaits. It’s now up to conservatives to provide the governing vision that will allow them to seize it.
