According to NARAL:
NARAL Pro-Choice America ran independent-expenditure campaigns aimed at persuading and motivating pro-choice women voters in six targeted congressional districts – Arizona’s 1st, Arizona’s 5th, Arizona’s 8th, Iowa’s 1st, Pennsylvania’s 7th, and Pennsylvania’s 8th. Five of these six pro-choice congressional candidates were victorious. Greenberg Quinlan Rosner Research conducted a series of post-election surveys among these targeted pro-choice women voters that provides strong evidence that the issue of choice made a real difference in these races. NARAL Pro-Choice America’s efforts to persuade and turn out pro-choice women voters had a positive and measurable impact on the outcomes of these races.
