No candidate in modern political history has been wiped out with young people — in a two-way contest — quite like Hillary Clinton. Up to 89 percent of voters under 30 backed Sen. Bernie Sanders of Vermont over Clinton in the New Hampshire Democratic presidential primary, and Sanders's progress in the Nevada and South Carolina contests has been aided immensely by young voters.

This is a real source of frustration for the voters who 1) support Clinton and 2) are not young.

In conversations last weekend, as Sanders and Clinton campaigned across Nevada, older women who backed Clinton said they understood, and sort of pitied, the reasons why young voters were flocking to Sanders.

"The presidency is not some jet ski that you glide over the waters of discord," said Linda Overby, a 58-year-old artist who rallied for Clinton in Henderson, Nev. "It's a cruise ship that you slowly, slowly, turn the right way."

In about 20 short conversations, Clinton supporters never pretended that their candidate was where she needed to be to win. ("I want to see a woman president before I die," said one Clinton voter, Mary Claiwer, half in jest and half in sorrow.) They just differed on the reasons, with the blissful ignorance of young voters emerging as one of the few that made sense.

"I don't think most of them have read her books," suggested Judy Barcelo, 60, at a Clinton event in Reno. "If they had, they would see the wealth of experience she's had. She knows the players. She knows the history. She knows the system. She knows how to get things done. Oh yeah, we can have free health care. I'm worried about him because of his age. I'd just hate to see him get elected, then keel over after three years."

Lori Santos, a former Hawaii politician who had relocated to Nevada, thought she understood the fall-off among young voters.

"I’ve been following Bernie Sanders for years, and I believe they have similar ideas, but she’s better equipped to deal with the world," she said. "He draws a younger crowd, and that’s due to his ability to teach. The younger crowd doesn’t know as much; it’s there to listen."

"She is so intelligent. She has all the answers in her brain. She has the experience. I love Bernie, too, but he doesn't have that," said Maureen May, 69, at the Reno event.

"I love him, and I love his energy, but it's too idealist," said Linda Brown, 64.

"Especially for this day and age," interjected May. "Personally I don't think he has a good enough grip on foreign policy."

Brown smiled. "My 30-year old-is brilliant," she explained. "He's a Hillary person. He's looked at the plans, and he's got a better idea of what can work and what can't."

There was just one caveat.

"My youngest is for Bernie."
