It’s a nonsense question. Clearly, anyone who believes the election was corrupted by the Dems and their surrogates don’t believe they believe that to be a big lie. They consider the big lie to be the claim the election was free and fair.
And what whoever believes there was no corruption of the election would not call that claim a big lie either. How would you answer the question,
" Do you believe the big lie that the election was free and fair ?"
