To understand why Mitt Romney has triumphed over his rivals for the Republican presidential nomination, look no further than March's disappointing job numbers. With growth fragile and petrol prices soaring, the economy is Barack Obama's gaping weak spot, and Republican primary voters have backed the candidate best equipped to exploit it. Yet it is very far from clear what they are getting. Blame that, in part, on a nominating contest that repeatedly veered into ir-relevancies. But blame the candidate, too. In the past year Mr Romney's views have metamorphosed worryingly as he has tried to protect his flank against a succession of conservative challengers. It is no exaggeration to say that there are now two Romneys when it comes to economics (see page 43).
