Pew Research: Rick Perry received the most favorable coverage of any candidate for president during the first five months of the race, but now Herman Cain is enjoying that distinction, according to a new survey which combines traditional research methods and computer algorithmic technology to code the level and tone of news coverage.
…. One man running for president has suffered the most unrelentingly negative treatment of all: Barack Obama. Though covered largely as president rather than a candidate, negative assessments of Obama have outweighed positive by a ratio of almost 4-to-1. The assessments of the president in the media were substantially more negative than positive in every one of the 23 weeks studied. In no week during these five months was more than 10% of the coverage about the President positive in tone.
