This is a very long comments thread and I haven't read all of the comments - so if someone else already made this point, credit to them.
Pro-Life vs Pro-Choice. Neither term accurately depicts the majority position in this country. Neither the Dems or Repubs represent the majority position.
The majority opinion happens to be that abortion should be legal during the first trimester, severely restricted during the 3rd trimester (limited to the life of the mother exception (LOM) ), and a varying degree of restriction during the 2nd trimester. This doesn't appear to be pro-life or pro-choice, which has become an unrestricted position.
