Jeff Greenfield: “The key lesson we forget every four years is that the nominating process stands in sharp contrast to the general election, where ‘fundamentals’ often hold sway. While I’m skeptical about the predictive ability of academics and experts to call an election a year or two out, there’s good evidence that a combination of variables—mostly, but not exclusively economic—can provide a useful, if sometimes blunt instrument for gauging the outcome of an election.”
“The history of primary elections, by contrast, suggests that they might as well take place on a different planet. The presidential nominating process usually involves a number of contestants. It moves by fits and starts; candidacies can rise, fall, revive and collapse with breathtaking speed. Again and again, months, even years of assumptions are thrown into a cocked hat by a sudden surge or implosion of a campaign.”
“It’s a history that should lead any political journalist to question just how much the ever-increasing tonnage of pre-primary coverage really adds anything useful to our understanding of the process.”
