There’s definitely incentive for that from both candidates. If they talk about how ahead they are in the pills, people will neglect to vote. If they talk about how they’re behind, then it’s a foregone conclusion and people won’t bother to vote.

If they preach about how close the polls are then it gets people worried enough to actually turn out and vote.

At this point I only seem to hear about polls directly from candidates or PACs so it’s hard to know what the biases are.
