Carol Evans approves of Donald Trump's immigration policy. She gives him credit for the strong economy. But the Republican from the affluent Milwaukee suburbs of Waukesha County, a GOP bedrock in Wisconsin, just can't commit to voting for Trump in next year's U.S. presidential election like she did in 2016.

"I just don't like the way he talks about other people," Evans, a 79-year-old retired data entry supervisor, said recently as she walked through a shopping mall in Brookfield, Wisconsin, days after Trump fired off a racist tweet at Democratic congresswomen.

The president's recent return to racial politics may be aimed at rallying his base of white working-class voters across rural America. But the risks of the strategy are glaring in conversations with women like Evans.
