What do we know about voters who say "don't know" in election polls?

Abstract

"With less than a week to go in the 2019 UK election, many people are undecided. And with margins so narrow, the people who still say they don't know who they will vote for could have a significant influence on the outcome. Ongoing research at the University of Manchester, using international survey data and in-depth interviews, is examining the nature of what it means to state that you 'don't know' when you are asked who you are going to vote for in an election."
