Did Romney adopt his pro-abortion views because of polls?

From the Daily Caller:

During his unsuccessful run against Sen. Ted Kennedy in 1994, Mitt Romney decided that he would run on a pro-choice platform after being advised that a pro-life candidate could not win in liberal Massachusetts.

The revelation comes from a new book, “Mitt Romney: An Inside Look at the Man and His Politics,” by journalist Ronald Scott. Journalist Byron York reported on Scott’s disclosure in an article published Friday in The Washington Examiner. . . .
