Support for allowing Central American refugees into the U.S. has grown from 51% in December to 57% in a July Gallup poll, even as Donald Trump continues to try to turn his cruelty toward asylum-seekers to his electoral benefit.

Much of the growth in support came from Republicans, rising from the rock-bottom level of 14% to 24%. Independent support grew from 52% to 58%, while support from Democrats edged up slightly from 82% to 85%. This growth comes despite Trump’s best efforts to appeal to voters’ worst impulses. Maybe most Americans don’t like seeing their government inflict suffering on vulnerable people?

According to 39% of those polled, the border situation is a crisis, while another 35% called it a major problem. That level of intensity combined with majority—and growing—support for letting refugees into the U.S. suggests that this may not be the big winning issue Trump has counted on it being.
