A hard-fought presidential primary campaign is obscuring the uncharacteristic degree of unity within the Republican party. It has reached a conservative consensus on most of the pressing issues of the day. All of the leading candidates, and almost all of the lagging ones, support the right to life. All of them favor the repeal of Obamacare. Most of them support reforms to restrain the growth of entitlement spending. All of them favor reducing the rate to levels that will make the U.S. a competitive location for investment. Almost all of them seem to understand the dangers of a precipitate withdrawal from Iraq and Afghanistan, and of a defense policy driven by the need to protect social spending rather than the national interest. Conservatives may disagree among themselves about which candidate most deserves support, but all of us should take heart in this development — and none of us should exaggerate the programmatic differences within the field.
Just as heartening, the White House seems winnable next year, and with it a majority in both houses of Congress, so that much of this conservative consensus could actually become law. A conservative majority on the , a halt to the march of regulation, free-market health-care policies: All of them seem within our grasp. But none of them is assured, and the costs of failure — either a failure to win the election, or a failure to govern competently and purposefully afterward — are as large as the opportunity.
