The only thing any 'poll' measures is, it is a measurement of how people answer a 'poll'.
It is not truth. It is not reality. It is simply a measure of "what people tell you". It is nothing more than that.
The reality is much darker. Many women suffer lifelong trauma from having an abortion. Every time they hear a crying baby, they could actually breakdown, thinking it is their own. When they see a baby, they wonder what theirs would have looked like.
There are deep psychological and hormonal aspects to pregnancy which cannot be simply 'dismissed'. It does not work that way. Unless you are a psychopath.
However, America is not currently suffering from a shortage of psychopaths. But, 95% would be a fairly high estimate.
