Clinton’s likeability remains a criticism even now, with some suggesting that it may cost her voters in her 2016 presidential bid.

Kelly Dittmar, a researcher at Rutgers University’s Center for American Women and Politics, told Time magazine: “What research from the Barbara Lee Family Foundation finds is that likability matters more for women candidates than for men. In other words, voters are much more comfortable voting for male candidates that they don’t like, but think are qualified to serve.

“For women, likability and qualifications are tied together in voters’ minds. They must demonstrate both traits to earn voter support.”

She continued: “It’s no surprise, then, that we seem to spend a lot more time worrying about how likable Hillary Clinton is than we do about whether or not we want to have a beer with Donald Trump.”

As a result of this, we have seen Clinton challenged by reporters on numerous occasions as to why she thinks that voters don’t like her – and Trump has yet to be asked the same.
