NEW YORK: “Bimbo,” “dog,” “fat pig”—Donald Trump has never minced his words about women he doesn’t like, but prolific insults and personal attacks on prominent females may cost him the election. This week America’s extraordinary presidential campaign descended to new lows when the billionaire and his main challenger for the Republican nomination, Ted Cruz, escalated their bitter feud, taking to social media to clash over two unlikely figures: their wives. Before the episode was over, Trump had tweeted a picture of his third wife, Melania, a former model, next to an unflattering photograph of Cruz’s wife, Heidi. Cruz reacted with fury. The real estate mogul posted the tweet after an anti-Trump coalition unveiled a controversial campaign ad using a magazine photo of Melania posing nude in his private jet 15 years ago. The incident likely did little to boost Trump’s ratings among women in a week when opinion polls revealed the very depth of the problem he faces with females. Thirty-nine percent of Republican women have an unfavorable opinion of Trump, according to a CNN/ORC poll. Meanwhile a survey from Quinnipiac University found that 60 percent of women would “definitely not” vote for Trump in the November presidential election. These are damning finds, especially when women outnumber men at the ballot box. In the 2012 presidential election, women accounted for 53 percent of turnout.
