Exit poll data can only be used this way if exit polls are mandatory, which they are not.
Exit polls are self-selecting, and statistically useless for mathematical proofs like this.

Yep, self-selected surveys of less than half of one percent of the voters are a better indicator than counting the votes of everyone.
