By Jim EllisJune 28, 2018 — Democrats have high hopes of converting a northern New Jersey seat that has only elected Republicans during the past 34 years, and a new Monmouth University poll (June 22-25; 406 NJ-11 registered voters) projects a toss-up 11th District contest. The two major party nominees, chosen in early June, are state Assemblyman Jay Webber (R-Morristown) and attorney and Navy veteran Mikie Sherrill (D).
Monmouth polling is experimenting with new sampling methods that involve three different turnout projection models. Their full sample, or “potential” voter model is one that tests only people who have voted in at least one election since 2010 or who are newly registered voters. The second model is what they term a “standard midterm” sample, and the third is in place to monitor a “Democratic surge,” if such were to develop.
The latter phrase has been used frequently in polling and in political commentaries, but there is little evidence of a substantial increase in Democratic primary voting from most states. At this point, national turnout models based solely upon 2018 primary voter turnout suggest a pattern that is closely aligned with a typical midterm performance. So far, more Democrats have been voting in states that normally vote Democratic, and more Republicans are participating in places where GOP candidates dominate.According to the full sample model, Democrat Sherrill leads Republican Webber by a scant 40-38 percent. Under the typical midterm model, the Democratic advantage increases to four points, 44-40 percent, but is still within the polling margin of error. Under their potential “Democratic surge” model, which may well prove illusionary when actual votes are counted, Sherrill increases her advantage to 45-39 percent.
The sample is weighted, but the draw does include more Independent voters (plus-three percent) than the raw percentage district total, and is four points less Democratic. But, the weighting formula is supposed to neutralize such discrepancies.
