You point to the LDS leadership flip flops on key doctrines (no argument there) and then appear to claim that Romney's flip flop on issues is inherent in his faith. I rather think it's inherent in his being a politician.
I don't think you would argue that Fred Thompson exemplified Mormon ideology when he flip flopped on CFR.
Well, nobody who's in politics a while stays static. There are going to be both some changes for the better & some for the worse.
So you're right in one sense. Politicians change. Politicians flip flop. (And the same is true w/us humans spiritually, relationally, emotionally, etc.)
But there's gotta be some big dividing line between public policy wayward outbursts and just plain double-mindedness as one big pattern.
Of the list I gave you on Romney's "gumbility," the three or so things that convinced me of his double-mindedness were..
(a) coming out with a pro-Boy Scouts and anti-Boy Scouts statement in the same breath...back to back sentences...in 1994; and...
(b) undergoing a supposed "pro-life" conversion in Nov. 04 only to say he was fully "pro-choice" in late May 05; and...
(c) telling a Fox interviewer in Aug 07 that in his mind he always thought of himself as being "pro-life"--not "pro-choice."
You can also include his being against civil unions, and then being for them. (Moving leftward).
It just seems that social policy wise I don't see the LDS erecting social policy stances or theological stances based upon an everlasting, universal absolute foundational basis. I mean, if polygamy was God's "Everlasting Covenant" for all peoples in all times--as LDS "Scripture" still contends (see D&C 130)--then the LDS god would not be strong-armed by some peasily little earthly government residing in some peasily little district called, "Columbia." Nor would such a god be a respecter of slave owners that He would be afraid of giving the gospel or baptizing slaves, as D&C 134:12 contends.
LDS know they have a god who not only does about-faces, but is two-faced. "god-liness" = becoming like the god you worship and admire.
To end on a more "upbeat" acknowledgment of LDS moving rightward on some things, it's nice to know that the LDS church has been trying to protect marriage for a number of years now...but when I think about how they were the ones militating against it for 55 years...it makes me think, "What happens if the Mormon god changes his mind again on a key social policy?"
Now for YOU to contend that the LDS god won't do that--or that theology doesn't overlap with public policy--then you just don't know enough about 19th-century history and what our government had to do to kick polygamy into a few southwest desert communities.
