Huckabee didn’t lose the nomination because he’s wrong about evolution. That had nothing to do with it.
2 questions:
(1) What definitive science do we have to prove evolution as right, and then his position, as wrong?
(2) Why did he lose the nomination?
(2) Why did he lose the nomination?
As to question (1), go to your library, or take some college classes, or just peruse the internet. There's a wealth of information out there and it certainly wouldn't fit into a single response here, which I suspect you'd categorically reject anyway.
As to question (2), he didn't get enough votes.
I think, because he is too liberal. He only got as far as he did because is not Mormon.
