In a historic moment in the U.S., a woman will become the presidential nominee of a major political party, but some political commentators notice a generational difference in the level of excitement following this event.

For women of a certain age, seeing Democrat Hillary Clinton on the cusp of breaking through the country's ultimate glass ceiling is a big deal, said Elizabeth Word Gutting, a Washington, D.C.-based writer and the program director at the PEN/Faulkner Foundation.

"I think there is an appreciation from women of my mom's generation for the accomplishments that Mrs. Clinton has achieved that allude women of my generation because we haven't gone through those same struggles," Word Gutting said.

While that isn't a reason enough to vote for Clinton in November, there is a sense of urgency about casting a vote for the nation's first woman president, Word Gutting said.

Word Gutting recently wrote in the New York Times about the struggles her mother endured after her first husband was killed in a car crash, leaving her to raise a newborn son on her own.

The circumstances led to a loss of power for her mother, Word Gutting said. The car insurance company revoked its coverage, credit cards were suddenly canceled, she no longer was eligible for loans, she was continually passed up for jobs that eventually went to men and she was sexually harassed at temporary workplaces.

For the first time in her life, her mom sees someone who can directly relate to her own experiences in a strong position to become president, Word Gutting said.

Word Gutting recognizes a difference in the significance of Clinton’s nomination between her mom and herself.

"I was sitting on my couch with tears running down my face because this was such an exciting moment," she said. "But I think for my mom, and for women in Hillary's same generation, there is a 'finally won feeling,' that this is so hard earned."

Perhaps because younger voters take women's progress for granted, there isn’t a heightened awareness of just how historic Clinton's campaign truly is, Word Gutting said.

It might be a symptom of the political scars anyone serving in public office for more than two decades might get, as well as the feeling of inevitability surrounding her nomination, Word Gutting said.
