Her view is pretty much mainstream, and if the GOP wants to win it will stick with government of the people, by the people. If you try to govern according to the ideology of 18% of the voters you will get 18% of the vote (unless you lie to people and they believe you). You won’t get much if anything done if you stick with the 18% as opposed to the majority who want limitations on abortion.
There is no point to a GOP that allows babies to be murdered.
