We wouldn't need politicians if all they did was repeat opinion polls. And very very few politicians say that they were wrong or that they stand corrected- they'll just blame their earlier comments on "it was a different time" or some similar nonsense.

To admit they were wrong would be to say everyone who previously voted for them was also wrong. We don't have that much bravery from most of our politicians.

Editing to add: of course, the real reason nobody expects them to ever say they were wrong is because nobody trusts they actually fully believe what they say in the first place.
