What did the men who would be president talk about during last week’s prime-time Republican debate? Well, there were 19 references to God, while the economy rated only 10 mentions. Republicans in Congress have voted dozens of times to repeal all or part of Obamacare, but the candidates only named President Obama’s signature policy nine times over the course of two hours. And energy, another erstwhile G.O.P. favorite, came up only four times.

Strange, isn’t it? The shared premise of everyone on the Republican side is that the Obama years have been a time of policy disaster on every front. Yet the candidates on that stage had almost nothing to say about any of the supposed disaster areas.

And there was a good reason they seemed so tongue-tied: Out there in the real world, none of the disasters their party predicted have actually come to pass. President Obama just keeps failing to fail. And that’s a big problem for the G.O.P. — even bigger than Donald Trump.
