John Cornyn and Ken Paxton’s Texas Republican Senate runoff has become a contest of attack ads, with pro-Cornyn groups spending substantially more. The article describes the campaigns’ messaging, polling and fundraising as early voting approaches.
Pro-Cornyn groups had outspent pro-Paxton forces by more than four to one through Wednesday, according to AdImpact. The article says ads from both sides have turned increasingly negative: Cornyn-aligned groups attack Paxton’s conduct, while Paxton’s campaign and allies criticize Cornyn’s record and support for Trump. Cornyn’s campaign also ran an ad touting his border-security efforts and law-enforcement endorsements.
The article reports that public surveys and internal polling point to a close runoff, while noting that the campaigns’ internal polling differs. It also compares fundraising, describes former President Donald Trump’s decision to remain uncommitted, and reports that Democrat James Talarico has raised more than either Republican candidate.
