WASHINGTON — The first questioner at an Iowa Democratic town hall on Monday night told Hillary Clinton to her face that young voters think she’s dishonest.

“It feels like there’s a lot of young people like myself who are very passionate supporters of Bernie Sanders,” Taylor Gipple told Clinton at the CNN event. “And I just don’t see the same enthusiasm from younger people for you . . . I’ve heard from quite a few people my age that they think you’re dishonest.”

Clinton’s face dropped.

“They throw all this stuff at me and I’m still standing,” she replied, and insisted the ongoing attacks on her amount to “nothing.”

“I’ve been on the front lines of change and progress since I was your age . . . I’ve taken on the status quo time and time again,” Clinton said.

Another questioner said he was a “lukewarm” supporter of hers until he saw how she endured 11 hours of testimony before the House Benghazi committee, and now he is “gung-ho.”

Moderator Chris Cuomo asked Clinton whether her apology about using a private email server as secretary of state amounted to her conceding that she had made an error in judgment.

“I’m not willing to say it’s was an error in judgment because nothing that I did was wrong. It was not in any way prohibited,” Clinton responded.

At the same event, Sanders, a self-described Democratic socialist, defended his plan for a government-funded health care program for all Americans.

And to fund it, he pledged, “We will raise taxes. Yes, we will.”

He insisted that in the long run, it would save the middle class money.

He also noted his vote against the Iraq war, his vow to reform Wall Street, and his early opposition to the Keystone Pipeline.
