New Hampshire: Sanders 29, Buttigieg 17, Biden 14, Warren 13

The 78-year-old Sanders does particularly well with younger voters. According to the WBUR poll, he has the support of 52% of Democratic voters under 30. That includes 29-year-old Elizabeth Ahearn, an independent from Tuftonboro, New Hampshire, who said she is backing Sanders because he is pushing for Medicare for All.”

“I have a variety of significant health issues,” she said. “And everything’s expensive. So it would be wonderful if we could have health care for all.”

Ahearn believes Sanders can take care of another one of her priorities: defeating President Trump.

“It’s very important to me,” she said. “I nearly left the country permanently in 2016. I think he can do it.”
