Bernie Sanders’s Wife Jane O’Meara Sanders, His Closest Adviser

— -- Before Jane O’Meara Sanders met her husband, she was told she sounded like him.

A former mayor of Burlington, Vermont, who was running for his fifth term informed her of this. She was a community organizer who stood up in a meeting and made a few suggestions.

“The mayor said, ‘Now you sound like Bernie Sanders,’ and I said ‘Let’s organize a debate,’” she recalled.

That debate was the first time Jane saw Bernie.

“He spoke and it was unbelievable,” she said. “I just felt that he embodied everything I believed, and I was on board right away.”

When they met, Jane was a single mother of three.

“He understood what my concerns were,” she said. “Worrying about childcare, worrying about the cost of housing, worrying about how am I ever going to send the kids to college.”

The two have been married for 27 years. Between them, they have four children and seven grandchildren.

Jane has a doctorate in leadership and policy studies, is a former college president and has served Vermont on a volunteer basis over the years. She is one of her husband's closest advisers -- so close that her desk is directly next to his in his campaign office.

She said it hasn't been too difficult balancing being a political adviser and a wife.

“I think since it has always been that way from the beginning of our relationship,” she said. “We’ve always talked issues. We’ve always creatively solved things together.”
