Polling Conflict in Nevada;
Dr. Oz Draws Closer in PA;
Two Polls, Different Results

By Jim Ellis — Aug. 29, 2022

Senate

Nevada: Polling Conflict — The Nevada Senate race is one of the most competitive and important statewide contests in this midterm election cycle, and two polls conducted within the same sampling realm report drawing opposite conclusions. Suffolk University, polling for the Reno Gazette Journal (Aug. 14-17; 500 likely Nevada general election voters; live interview), projects Sen. Catherine Cortez Masto (D) to be leading former Attorney General Adam Laxalt (R), 45-38 percent. Conversely, The Trafalgar Group (Aug. 15-18; 1,082 likely Nevada general election voters; multiple sampling techniques) sees a complete opposite picture. They find Laxalt holding a three-point edge, 47-44 percent.

It is not particularly surprising to see The Trafalgar Group with different results since their polling methodology is unique. Their accuracy rate, however, is among the best in the survey research industry.

Pennsylvania: Oz Drawing Closer — Despite what even a casual observer would perceive as Pennsylvania Republican Senate nominee Mehmet Oz’s campaign going poorly, two new statewide surveys find him trailing Lt. Gov. John Fetterman (D) by only four percentage points as the two research firms arrived at exactly identical ballot test results.

The pollsters, The Trafalgar Group (Aug. 15-19; 1,087 likely Pennsylvania general election voters; multiple sampling techniques) and Emerson College (Aug. 22-23; 1,034 likely Pennsylvania general election voters; interactive voice response system, online & text) both see Fetterman leading Dr. Oz, 48-44 percent. On the other hand, the new Franklin & Marshall College poll (Aug. 15-21; 522 registered Pennsylvania voters; live interview), with a much higher error rate than the other two, finds Fetterman’s advantage to be 43-30 percent.

House

MI-10: Two Polls, Same Time, Different Results — Regular Michigan pollster Mitchell Research, again surveying for the Michigan Information & Research Service (Aug. 16-21; 429 ikely MI-10 lgeneral election voters), finds former US Senate Republican nominee John James leading ex-Macomb County prosecutor Carl Marlinga (D), by a 47-38 percent clip, well beyond the polling margin of error. The Marlinga campaign countered with a Target Insyght survey (Aug. 16-18; 400 likely Michigan general election voters) that gives their candidate, Marlinga, a slight 47-45 percent edge. The new 10th was drawn as a highly competitive district, so a close finish here is clearly on the political horizon.

Governor

Pennsylvania: Same Pattern as Senate — The three pollsters that tested the Pennsylvania Senate race, The Trafalgar Group, Emerson College and Franklin & Marshall College (see PA Senate above) the same partisan pattern is also appearing in the governor’s race. The Trafalgar and Emerson results are similar, and the F&M conclusion greatly differs, though they all agree on the race order.

In the governor’s race, The Trafalgar Group finds Attorney General Josh Shapiro (D) leading state Sen. Doug Mastriano (R-Fayetteville), 49-45 percent, while Emerson posts a similar 47-44 percent division. Like in the Senate race, Franklin & Marshall sees the Democratic performance in much better position. Their ballot test projects AG Shapiro with a stronger 44-33percent advantage. The stated margin of error factor on the Trafalgar poll is 2.9, while Emerson’s is an almost identical 3.0. The F&M error factor, however, is listed as 4.3percent.
