General Giap is alleged to have said in his memoirs that they lost big in the Tet offensive; I haven't read them so I can't say for sure.

A member of his staff, a Col. Bui Tin had an interview published in the Aug 3 1995 Wall Street Journal saying the same thing.

Q: Was the American antiwar movement important to Hanoi’s victory?

A: “It was essential to our strategy. Every day our leadership would listen to world news over the radio at 9AM to follow the growth of the antiwar movement. ...Those people represented the conscience of America. The conscience of America was part of its war-making capability, and we were turning that power in our favor. America lost because of its democracy; through dissent and protest it lost the ability to mobilize a will to win.”
