Here is a non-exhaustive list of recent GOP candidates that oppose abortion in cases of rape, a very unpopular position, and lost their elections:
Angle, Mourdock, Akin, O'Donnell, Miller, Buck, West, Paladino, Walsh
A Gallup poll found that only 22% of those polled believed women should be prevented by law from abortions in cases of rape.
It is on such bases, that people like this young woman conclude Republicans hold views outside the mainstream, and so warn.
I'm sure that it would be even less than 22% for females and for younger voters.
