Crowley Holds Narrow Lead Over Tiffany in Early Post‑Primary Poll

Overview

• Platform Communications' Badger Battleground survey of 500 likely voters conducted Aug. 12–13 shows Democrat David Crowley at 48 percent and Republican Tom Tiffany at 44 percent with a margin of error of ±4.4 points.
• Crowley leads more decisively among independents in the poll, with 42 percent to Tiffany's 30 percent, a bloc both campaigns see as central to deciding the race.
• The poll finds Crowley with a net-positive favorability around 43 percent favorable versus 26 percent unfavorable while Tiffany is viewed more unfavorably than favorably at roughly 43 percent unfavorable and 38 percent favorable.
• Both campaigns announced seven-figure fall ad plans and are racing to define messages and secure endorsements, with Crowley saying he will not campaign with streamer Hasan Piker and Tiffany declining to say whether he wants President Trump to campaign in Wisconsin for him.
• Wisconsin's history of tight statewide margins means small shifts in turnout or targeted advertising could swing the outcome, so watchers should track independent voter movement, ad spending patterns, and how each campaign reshapes voter views over the next weeks.
