In my estimation, this poll (from Gallup) accurately measures the reality: Pro-Choice Americans at Record-Low 41%. As shown in their tracking chart, more than ever, the killers of God's innocent children are held in increasingly low regard:
Given that the Gallup organization is not particularly friendly to the Christian Conservative movement, I'd surmise that those favoring baby killers are actually lower than 41%. I'll also add that, like the term "gay" being co-opted by the homosexualists, the phrasing "pro-choice" doubtlessly skews the results in the favor of the evil abortionists and their well-financed lobby.
I’ve heard some Christian conservatives like Steve Deace say that these polls don’t necessarily reflect how people feel on legality or Roe vs. Wade but just if they would personally have an abortion or not. The wording of Gallup’s question is too vague to make a conclusion on that.
The huge swing back and forth in the last 3 years also perplexes me.
As the past election taught us (again), bare demographic numbers don’t spell the entire story of the influence of a movement.
