Executive Summary of the Media Primary Study

This report analyzes coverage and tone of presidential contenders in the 2012 U.S. election race during its first phase (May 2 to October 9, 2011), using a combination of traditional content analysis and Crimson Hexagon's algorithmic technology to track coverage across 11,500+ news outlets and hundreds of thousands of blogs.

Methodology

• Quantitative Data: Based on PEJ's News Coverage Index, coding news exposure and tone.
• Algorithmic Analysis: Crimson Hexagon software analyzes text for categories like positive, neutral, negative using statistical word patterns. Unsupervised by humans in classification post-training. Validated with high reliability (97% match to human coding).

Key Findings Overview

• Newspaper Coverage: Rick Perry dominated attention in traditional media, with balanced or mixed tones initially, declining later. Barack Obama was the top newsmaker overall but suffered from overwhelmingly negative tone (9% positive, 34% negative). Blogs amplified negativity and showed harsher critiques than print media.
• Dynamics: Coverage shifts correlated with events (e.g., Perry's debates, Cain's straw poll victories) and inter-party treatment variance in blogs.

Detailed Breakdown by Candidate

• Rick Perry: Received 17.5% of news exposure, highest in August-September. Tone shifted from positive (32% neg./pos early) to slightly negative due to debates/polls. In blogs, he ranked 4th with largely negative reception (40% neg., 21% pos.).
• Mitt Romney: Second in news exposure (12.6%), consistent mixed tone (26% pos., 27% neg.). Blogs mirrored similar tone.
• Herman Cain: Grew rapidly in coverage from September onward, with a turn to positive tone preceding poll gains (early 2021). Blogs viewed moderately favorably.
• Michele Bachmann: Rollercoaster: strong early positive with debate wins, declined post-Perry emergence. Tone positive in 31% of coverage; blogs overwhelmingly negative.
• Sarah Palin: Non-candidate, but heavily covered in news (7.2% of exposure) and highly discussed blogs. Positive tone in news vs. predominantly negative blogs.
• Barack Obama: Dominated media exposure (8.8% of news, leading Republicans), with uncaptionable negative ratio (overall 33% neg.). Blogs marginally better tone but still harsh.
• Commonalities: Republicans with limited media presence (e.g., Santorum, Gingrich) faced constant criticism; social media acted as an amplifier for negative sentiments.

Summary on Media vs. Blogs

Blogs offered less overall coverage but harsher, static tone analyses, unlike media. Inter-partisan coverage and candidate critique varied, with blogs often emphasizing ideology.

Timeline Insights

Coverage evolved through four phases: announcement surge, policy debates focus, debt crisis overshadowing, and Perry's election surge drove narrative changes.

Conclusion

The early 2012 primary season highlighted divergent media landscapes: traditional sources offered broader, sometimes balanced views, while online discourse featured extreme polarization. Cand الرئيسانl coverage shifted dynamically around key policy moments and individual performances.
