I go back and forth on this, but there is a school of thought that says that abortions will eventually guarantee a permanent liberal minority. In this year's election, there will be 18,336,576 in the Voting Age Population missing because of abortions between 1972 and 1986. FWIW: http://www.opinionjournal.com/extra/?id=110005277
But Bill, you have to consider all the women who lost theirs lives attempting illegal abortions before Roe v Wade... ...all 45 of them in 1974 according to the US Bureau of Stats.
this is going to sound like something one of the leftist lunatics would say but i'll proceed with my thought anyway.... I am usually against abortion but then I think about Michael Moore and I really wish his parents would have gotten one.
