This month, about half (47 percent) of Republican female primary voters said they could not imagine themselves voting for Trump. (About 40 percent of male GOP primary voters said the same.) Compare that to their relative willingness to accept Trump's rivals. Only about three in ten female Republican voters say they can't imagine backing Ted Cruz (32 percent) and John Kasich (27 percent). The poll, which was taken before Marco Rubio exited the presidential race, also showed that only 30 percent of GOP women couldn't imagine backing the Florida senator.
