Donald Trump usually uses his gift for bombast to whip up anger that works to his political advantage. But it's also his opponents' greatest weapon against him.

Last Tuesday, during a victory speech after sweeping the Acela Primary, Trump boldly declared that Clinton's success could be attributed to her exploiting her identity to win votes.

"Frankly, if Hillary Clinton were a man, I don't think she'd get 5% of the vote. The only thing she's got going is the women's card," he said, repeating a claim he's made in the past.

Clinton made use of her favorite rejoinder during her victory speech later that evening: "If fighting for women's health care and paid family leave and equal pay is playing the woman card, then deal me in!"

But that wasn't the end of it. This time the Clinton campaign used Trump's outrageous rhetoric as a fundraising rallying point for her supporters. According to a New York Times report, the results were extraordinary — she pulled in a personal record-breaking $2.4 million during the last three days of April, "through emails and the purchase of related products ... [including] a hot pink 'Woman Card' ('Congratulations! You're in the majority,' the card reads), 'Deal me in' T-shirts and a deck of cards with statistics like 'Only 5% of Fortune 500 CEOs are women.'"

Trump should be wary of continuing to cultivate his reputation as an unabashed misogynist — women make up a majority of the general electorate, and an April Gallup poll showed a staggering 70% of women viewed him unfavorably. Exploiting prejudice has served him well as he's approached the Republican nomination, but should he win it, he's going to have to remember that anger and fear will likely motivate those who oppose him just as much as it will inspire those who support him.
