Political Trivia for July 26

Today’s question comes (again) courtesy of cqpolitics.com, and it’s a tough one:

How many years after the historic Nixon-Kennedy debates in 1960 was the next debate between the Democratic and Republican presidential nominees?

No googling, just guessing. If you have a trivia question to suggest, email it to mojotrivia@gmail.com.

Update: As two commenters correctly guessed, it was 16 years later, in 1976.
