"To me, that is not just a concern for our generation, it's a concern that calls on us to build an alliance among generations to try to make sure that the future really is better than the past," Buttigieg, the former mayor of South Bend, Ind., said in answering a question from an audience member in New Hampshire.

In the live CNN event on Thursday night, Buttigieg's answer did not compel the audience at Saint Anselm College to break into applause.

Buttigieg and Sanders, 78, just finished in a dead heat in Iowa, with both sides declaring victory in a contest marred by delays, errors and inconsistencies.

The campaign received some blowback after the clip made the rounds on social media from supporters of Sanders.
