September 11, 2013 - Quinnipiac University Poll Accurately Measures Outcomes In New York Primary PDF format The Quinnipiac University poll accurately measured the results of the New York City Democratic primary for mayor and comptroller. A September 9 survey of likely Democratic primary voters by the independent Quinnipiac (KWIN-uh-pe-ack) University showed Public Advocate Bill de Blasio with 39 percent, followed by former Comptroller William Thompson at 25 percent, City Council Speaker Christine Quinn with 18 percent and 8 percent undecided. That poll noted that a few undecided voters could put de Blasio over the 40 percent mark needed to avoid a runoff election. Unofficial results on September 11 show de Blasio with 40 percent, Thompson with 26 percent and Quinn with 16 percent. The September 9 survey showed Manhattan Borough President Scott Stringer leading former Gov. Eliot Spitzer 50 - 43 percent in the comptroller's race. September 11 results show Stringer over Spitzer 52 - 48 percent. An August 7 Quinnipiac University New Jersey poll showed Newark Mayor Cory Booker leading U.S. Rep. Frank Pallone by 37 percentage points among likely voters in the Democratic primary for U.S. Senate. Booker won by 39 points. In more than 20 years of public opinion surveys, Quinnipiac University has developed a reputation for accuracy. From September 6 - 8, Quinnipiac University surveyed 782 likely Democratic primary voters with a margin of error of +/- 3.5 percentage points. Live interviewers call land lines and cell phones.
