From a press release:
(PEORIA) With just over two months to go in the race, a new poll conducted by Public Opinion Strategies of Alexandria, Virginia on August 18-20th shows Aaron Schock leading Colleen Callahan by a more than two-to-one margin with Green Party nominee Sheldon Schafer getting 2% of the vote.
The 400 sample size poll conducted throughout the 18th Congressional District shows Schock with a commanding lead throughout the district. The head to head match up showed Schock with 56% of the vote to Callahan’s 27% and Schafer’s 2%, with 13% undecided.
The question was simply worded, “If the election to U.S. Congress were being held today, for whom would you vote.. .Colleen Callahan, Democrat; Sheldon Schafer, Green Party or Aaron Schock, Republican? The three names were rotated in order as the question was asked of voters.
The Schock campaign released two polls it had commissioned by Public Opinion Strategies in the primary race and both showed Schock with substantial leads. His final vote totals were even higher however, earning 72% of the vote.
“Public Opinion Strategies is one of the most respected and accurate polling firms in the nation,” said Schock campaign manager Steven Shearer. “Some people questioned the validity of the polls we released in the primary campaign and even scoffed that Aaron’s numbers couldn’t possibly be that high, but Aaron’s margin of the vote confirmed those poll findings.”
“Without question the only poll that counts is on Election Day,” Shearer continued. “That is why Aaron Schock is working exceptionally hard to earn new support each and every day, just as he has done in each campaign.”
A memo of the results of the poll has been prepared by Public Opinion Strategies and follows this page, and is being publicly released to the media.
