Really deplore Donald Trump's tone of presidential campaign: Hillary Clinton

WASHINGTON: Democratic presidential frontrunner Hillary Clinton has said she "deplores the tone" of the presidential campaign of her Republican rival Donald Trump, who recently used a vulgar term to describe her, but is not surprised by his "hateful and incendiary rhetoric".

"I really deplore the tone of his campaign, the inflammatory rhetoric that he is using to divide people, and his going after groups of people with hateful, incendiary rhetoric," Clinton told the Des Moines Register in an interview in Iowa.

"Nothing really surprises me anymore. I don't know that he has any boundaries at all. His bigotry, his bluster, his bullying have become his campaign. And he has to keep sort of upping the stakes and going even further," she said in response to a question.

"I don't respond to him personally, because he thrives on that kind of exchange," Clinton said when asked about the personal attack against her by Trump which many said is sexist and below the belt.

"I think he has to answer for what he says, and I assume that others will make the larger point about his language. It's not the first time he's demonstrated a penchant for sexism.

"Again, I'm not sure anybody's surprised that he keeps pushing the envelope," she added.
