According to a Gallup poll taken in early May 2009, more people now consider themselves "pro-life" than "pro-choice". Since Gallup started asking this question in 1995 this is the FIRST TIME that has been the case. Click here for the details.
You know, there is a big demographic thing that could really affect all this, too. If the "pro-life" people have lots of children and the "pro-choice" people have few children it is just a matter of time. . . that is basic math.
When you read more about who has changed their mind, though, and the suggested cause in the article I think you will be surprised. :)
