- Loaded language — Highly charged language appears mainly as attributed ad copy or quotations.

This is Texas Tribune's own score. The Source Check scores are for WOAI and this article.
John Cornyn and Ken Paxton are relying on increasingly negative ads as they compete for the Republican Senate nomination in Texas. The spending gap has narrowed, and polling cited in the article suggests a close runoff.
Pro-Cornyn groups have spent more than four times as much as Paxton-aligned forces in the runoff, although the gap is smaller than it was in the March primary. The ads have attacked Paxton over his record and personal conduct, while Paxton’s campaign has attacked Cornyn’s tenure, positions and relationship with Democrats. Campaign representatives and a Republican strategist described the strategy as an effort to disqualify the opposing candidate rather than change voters’ minds.
The article reports that public and internal polls point to a close contest, while noting that the campaigns’ own surveys differ. It also describes President Donald Trump’s decision to delay an endorsement, the candidates’ fundraising, and Democrats’ hopes of benefiting from the Republican contest. Cornyn’s campaign has run an ad promoting his border-security work, while pro-Cornyn groups have continued their attacks on Paxton.
