Susquehanna Polling released a poll showing Obama with a two point lead over Romney in Pennsylvania. Today on their blog they have a fascinating post explaining their methodology and why the makeup of the electorate is likely to be quite different from 2008:
Recently two polls conducted by our firm showing President Obama narrowly leading Mitt Romney by 1 point (48% to 47%, sponsored by the Republican State Committee of Penna.), and a second released by the Pittsburgh Tribune Review on Sunday, September 23 showing Obama leading Romney by 2 points (47%-45%). Both margins conflict with other surveys conducted recently including one by the Philadelphia Inquirer (Obama +11) and Muhlenberg College (Obama +9). Following are answers to questions about our survey methodology as well as our basis for predicting a close election.
Our vote model for gauging the number of interviews conducted with voters of different demographic groups (things like party affiliation, racial background and age range, etc.) is a blend of turnout models from both the 2008 and 2004 presidential elections, but leans more towards 2004 VTO and is predicated on the belief that turnout this November will not be anywhere near ’08 levels when 5.9 million votes were cast.
First, our ratio of interviews conducted with Republicans and Democrats in our recent polls (49D – 43R) gives Democrats a 6-point advantage based on the fact that Democrats outnumber Republicans in actual registration. However, this ratio is slightly more Republican based on both national and state polling showing that Republicans are more likely to vote than Democrats this year given high intensity among Republicans who strongly disapprove of the President’s job performance. Nonetheless, this +6 Democratic advantage is only one point less Democrat than the 7-point advantage these same exit polls gave Democrats in the 2008 presidential election. Besides, simply conducting more surveys with Democratic voters (as some have suggested) doesn’t necessarily translate into more votes for President Obama when you consider that Mitt Romney is winning Democratic-leaning counties in Western Pennsylvania by ten or more percentage points. Nonetheless, it is entirely appropriate to sample Republicans one or two points higher than in 2008 if you believe as we do that voter turnout this November will have little resemblance to the last presidential election.
Second, our ratio of younger to older voters reflects turnout that is likely to be slightly higher with older voters given the lack of enthusiasm from younger voters. In our surveys, 18-44 yr. olds make up 30% of all interviews and voters 45 years of age and older represent the remaining seventy percent. For instance, according to 2008 exit polls voter turnout among 18-29 year olds peaked at 18%, but national and state polling proves interest among younger voters down sharply this year due to higher unemployment with younger voters and college graduates in particular. So conducting approximately ten percent of surveys with 18-29 year olds is a reflection of this lower anticipated turnout among these less-enthusiastic voters. Besides, the fact that Obama backers have suggested that over sampling older voters skews results in favor of Mitt Romney is a striking revelation in a state like Pennsylvania known for having the 5th largest population of senior citizens in the country.
Go here to read the rest. Too many pollsters are merely plugging in the 2008 electorate and badly skewing their polls to Obama. Don’t believe them. Keep your eye on the Rasmussen and Gallup tracking polls to have the best feel for the race.
