Is the SCOTUS nominee “outside the mainstream” on abortion?

A new Gallup Poll, conducted May 7-10, finds 51% of Americans calling themselves pro-life on the issue of abortion and 42% pro-choice. This is the first time a majority of U.S. adults have identified themselves as pro-life since Gallup began asking this question in 1995. According to US News and World Report, this development will keep the Republican Party marginalized. Also, DFLA are interested by another finding of this poll to note that for the first time in a decade, more men are against abortion than women, 54% of men to 49% of women. Democrats for Life

I'm not sure why this poll marginalizes Republicans as reported in US News. It just means Democrats don't vote their conscience when it comes to abortion.
