During his tenure in the U.S. House (1977 to 1984) Gore voted pro-life 27 times and had a 84% pro-life voting record.
In letters to a constituents, he wrote: “It is my deep personal conviction that abortion is wrong. I hope that some day we will see the current outrageously large number of abortions drop sharply.” (Letters from Sept. 15, 1983, August 22, 1984, )
In a May 26, 1987 letter to a constituent he wrote: “During my 11 years in congress, I have consistently opposed federal funding for abortions. In my opinion, it is wrong to spend federal funds for what is arguably taking of a human life. Let me assure you that I share your belief that innocent human life must be protected, and I am committed to furthering this goal.”
Ok, so explain how he was rated so low. You pointed out 1 issue that he quickly abandoned when it became politically expedient to do so. He was Pro life once...great, but again, he was rated VERY poorly overall when Perry supported him.
