Donald Trump has a problem appealing to female voters.&nbsp;So, when asked this week by a Nevada television station&nbsp;about some of his disparaging remarks, he had a terse reply.&nbsp;"A lot of that was done for the purpose of entertainment," Trump said. "There's nobody that has more respect for women than I do."Following last week's presidential debate, in which Hillary Clinton castigated Trump for his comments about a Miss Universe winner whom he called "Miss Piggy"&nbsp;after she gained weight and "Miss Housekeeping" for her Latina&nbsp;roots,&nbsp;his support among women has declined, according to polls.An NBC News/Survey Monkey poll taken after the debate showed 27%&nbsp;of likely female&nbsp;voters said the debate made them think worse of Trump. About 30%&nbsp;said their opinion of Clinton had improved.&nbsp;Throughout the campaign, Trump's poll numbers among women have been far from stellar.&nbsp;Clinton and her Democratic allies have hammered him&nbsp;in television and radio ads for his caustic comments that date back to the 1980s.Last year, after Trump faced tough debate questions from Fox News anchor&nbsp;Megyn Kelly, he speculated that it was because she was menstruating.&nbsp;Trump, who has also referred to actress Rosie O'Donnell as a "pig," defended himself during the debate with Clinton.&nbsp;"Hillary is hitting me with tremendous commercials. Some of it I said in entertainment, some of it said to somebody who has been very vicious to me, Rosie O'Donnell," Trump said. "I said very tough things to her and I think everybody would agree she deserves it and nobody feels sorry for her."
