I find it interesting that you don't even need to compare Mitt's old stances on all kinds of issues with his new stances to see how "convenient" his changes are. I mean just go back to 1994 with some of the YouTube clips of his debate against Ted Kennedy.
He says he will "sustain and support that [Roe-based] law" and that he would "sustain and support" a woman's choice [to abortion]. What few folks understand is that the word "sustained" to a Mormon is a sacred word.
LDS have that word several times in Doctrines & Covenants (LDS "Scripture"). "Sustained" is the word used by LDS grassroots members toward their dead "prophets," their living "prophets," and their general authorities. By "sustaining" these people, the entire belief system is committed to what they have revealed.
For Mitt to say he would "sustain" Roe and then not "sustain" Roe would be like a Mormon saying he would "sustain" his living prophet and then back out.
Likewise, Mitt covers all bases with his 1994 statement on the Boy Scouts, first saying the Boy Scouts should do what they want to do; and then saying in his next breath anybody of any "sexual orientation" "should be allowed to participate" in the Scouts.
Anybody that supports gay scoutmasters will never get my vote.
