Mitt Romney needed 15 weeks once the primary contests began to gain a secure hold over his party’s nomination for president. But he emerged as the conclusive winner in the media narrative about the race six weeks earlier, following a narrow win in his native state, according to a new report by the Pew Research Center’s Project for Excellence in Journalism that examines in detail the media’s coverage of the race.
After Romney’s tight victory in the Michigan primary on Feb. 28, news coverage about his candidacy became measurably more favorable and the portrayal of his rivals—particularly Rick Santorum—began to become more negative and to shrink in volume.
One main component of that shift in the narrative is that after Michigan, the news media began to view Romney’s nomination as essentially inevitable. Indeed, a close look at the coverage finds that references to delegate math and the concept of electoral inevitability spiked in the media the week after Michigan, rising twelve fold, for instance, on television news programs. From that point on, the amount of attention in the press to Romney’s candidacy began to overwhelm that of his rivals, and the tone of coverage about him, which had been often mixed or negative before, became solidly positive.
