There has been a fair amount of discussion in recent days about whether Republicans should try to defund Obamacare. The instinct to do something about Obamacare is right. But Republicans can learn something from the American people. As polls have consistently shown, Americans like the idea of delaying—and of repealing—Obamacare. But they don’t like the sound of defunding it. In terms of policy, either approach would produce essentially the same result. (Whether the Obamacare exchanges are delayed for a year, or its exchange subsidies are defunded for a year, the result would be no taxpayer-funded Obamacare exchanges next year.) Politically, however, framing the effort as one of delaying rather than defunding stands a far greater chance of success.
