From September 4 to 9, 2012, Hart Research undertook an online national survey of 1,206 registered voters on behalf of SEIA, including an oversample of swing voters (resulting in 762 swing voter interviews). The swing voter sample included only those respondents who did not indicate a strong or consistent partisan voting history. The margin of error for the full sample is ±2.8 percentage points.
