As of the most recently surfaced polling/news I can see right now, the key takeaway is that Bill Cassidy’s polling in Louisiana’s 2026 Senate race is moving between “strong lead” and “much tighter/behind” depending on the poll and matchup.[1][3]
What the latest poll coverage is saying (Louisiana Senate primary)
- A May 2025 report (Ragnar Research) described Cassidy leading among likely Republican voters, including favorable vs unfavorable figures and a hypothetical primary matchup where a larger share supported Cassidy.[1]
- A May 2026 report (Quantus Insights, per Newsweek coverage) described Cassidy trailing in the Republican contest, with Letlow ahead and Cassidy reported at a much lower figure in that poll’s results.[3]
One other recent “poll says it’s competitive” thread
- There’s also coverage suggesting polling has made the primary feel more competitive/uncertain than some expectations, though the snippet I’m seeing doesn’t include the full numbers.[6]
Quick clarification (so I fetch the right “latest” for you)
Do you mean (1) Louisiana Republican primary polls (Cassidy vs Letlow/Flemming/etc.), or (2) general-election polls (against a Democratic opponent)? Also, what date range counts as “latest” for you (last 24 hours, week, or month)?
