Despite recent setbacks, Hillary Clinton’s campaign remains serenely confident of victory because of their candidate’s strength among one crucial group in the electorate: white women. Actually, Hillary doesn’t even need a majority of this group; she just needs to come within ten points of the GOP candidate. In 2012, Romney won white women by a landslide margin of 14 percentage points. But Barack Obama still won the overall women’s vote because non-white females, nearly 30% of the women’s vote, gave him a three-to-one margin. The Clinton campaign knows they can’t replicate Obama’s historic appeal to blacks and Latinos, so they will focus on white females with feminist appeals to “woman power.” Republicans must counter with a strong female nominee for Vice President to preserve their strength among white women. A strong female also can perform better than any male in one key role of a running mate: as an attack dog against the Democratic presidential nominee.
