“ They are also largely commissioned by those with an agenda and are often loaded questions, with loaded lead up questions and large numbers of undecideds”

I don’t think that’s correct mate. The main pollsters use very similar and widely approved methodology. It doesn’t matter who commissions the polls, but even then it tends to be Yoon media organisations who commission them.

Numbers of undecideds are by no measure high, and are largely irrelevant as the undecideds are mostly those who do not vote.

It definitely is the 11th in a row as well. The one prior to that was a tie.
