From 538: "In 2008, 52 percent of voters in the New Hampshire Republican primary said abortion should always or sometimes be legal, according to the exit poll. Only 15 percent said it should always be illegal."
The pro-life side generally does much better when sometimes is further broken down. Because even someone who opposes rape and incest exceptions, but supports some maternal health exception would technically be sometimes.
Also, remember that the current issues being fought on are waiting periods, a 20-week ban, and defunding PP, not a total ban (at least until a couple SCOTUS nominees).
