The poll question

Was worded poorly.

So you have two choices. Was he full of shit, or was he telling the truth.

If I said yes, was I saying yes he's full of shit, or yes he was telling the truth?

That's why the only correct answer was "yes". Around half of america has no reading comprehension, or are big on the gray area of reality TV, that is, they felt the truth lay somewhere between such polar extremes.
