Via Byron York, a preview of a book by Boston journalist Ronald Scott:
According to Scott, Romney revealed that polling from Richard Wirthlin, Ronald Reagan’s former pollster whom Romney had hired for the ’94 campaign, showed it would be impossible for a pro-life candidate to win statewide office in Massachusetts. In light of that, Romney decided to run as a pro-choice candidate, pledging to support Roe v. Wade, while remaining personally pro-life.
Instead we may get a nominee with poll-driven conviction. As of 2005 the polls apparently showed that being pro-life was necessary to run for President as a Republican, so he changed his mind. Let’s hope the polls don’t change.
