Marquette Law School’s latest poll gave Wisconsin voters something to talk about — and gave Team Tiffany a grin. The survey shows Milwaukee County Executive David Crowley and U.S. Rep. Tom Tiffany in a dead heat among registered voters, with Crowley holding only a slim lead among likely voters. Conservatives are calling it “bad news” for Crowley, and not without reason.
What the Marquette poll actually says
The Marquette Law School Poll finds the governor’s race is tied among all registered voters at 44% each, with 12% undecided, and shows Crowley leading Tiffany 49% to 44% among likely voters, with 7% undecided. Marquette’s sample was under 1,000 registered voters, and their likely‑voter screen uses people who say they are “certain to vote.” That matters — it is not a crystal ball, it’s a snapshot.
The “August bias” claim: fair warning or partisan spin?
Conservative commentators point to a pattern: Marquette’s August releases have sometimes overstated Democratic strength heading into November. They say history suggests Crowley’s August numbers could be a high point. Marquette pushes back — it’s a well‑rated, transparent pollster, and August is simply a noisy month. Both sides have a point. The real truth is this: one poll is only one piece of evidence, but a tight poll is a smoking gun for the challenger.
Why methodology and timing matter
August polls can swing more than a weathervane. Marquette’s likely‑voter screen, the timing of interviews, and who answers the phone can tilt results. The poll also showed high partisan loyalty and a big edge for Crowley with independents in the likely‑voter sample — while a double‑digit undecided block among registered voters shows room to move. In plain terms: the poll is close enough that late events, turnout, or simple polling quirks could change the picture.
What this means for Crowley and Tiffany
For Republicans, the takeaway is simple: this race is winnable. For Team Crowley, the message is not to blame “August math” forever. Voters in the rest of Wisconsin already grumble about Milwaukee’s priorities, and the data‑center flap — “Data Center David” — gives Tiffany a clear attack line. Crowley’s record as county executive on taxes, budgets, and crime will be replayed nonstop. A tight Marquette poll hands Tiffany a punch list he can use in fall ads and debates.
Bottom line
Don’t treat one August poll as destiny, but don’t ignore it either. Marquette’s numbers make this a competitive governor’s race and hand Republicans momentum. Crowley can hope the August snapshot fades — or he can answer voters’ doubts now. Either way, Wisconsin conservatives should be sharpening their message and their turnout plan. Polls open doors; campaigns walk through them.
