Here are two more articles relevant to my recent post regarding undecideds. (See here and here.) According to the AP/Yahoo poll, almost one in ten voters remain undecided – a slightly higher number than what many of the other surveys are reporting. As the second article indicates, and as I alluded to in my earlier post, the difference is due in part to the question wording that pollsters use when asking respondents for whom they are likely to vote. As David Moore points out in the other article cited above, pollsters routinely push undecideds to make a choice. They also tend not to highlight in their stories the number of respondents who say they might change their mind. Why does this matter? Keep in mind that pollsters ask people who they would vote for if the election was held today – not who they think they will vote for on Nov. 4, the actual election day. In other words, there is room for voters who say they are leaning toward someone to change their mind even this late in the process. Consider that the 2004 exit poll found 9 percent of voters saying they had made up their minds in the three days before the election. In short, looking only at undecideds in any given poll may understate the number of persuadables remaining in the electorate. For example, the most recent ABC poll suggests that there are only 2% undecideds remaining. But in the fine print of the poll, you find an additional 3% who say there is a “good” chance they will change their mind. Among McCain supporters, 4% say they there is a “good” chance they might change their mind, but only 1% of Obama supporters say as much. In the CBS poll, fully 7% of Obama supporters and 9% of McCain supporters say their minds are not made up. In the Fox poll, 17% of Obama and 22% of McCain supporters indicate that they support their candidate only “somewhat.” None of these voters are considered “undecided”, however. But it suggests that there may be more room for movement in support for both candidates than the top-line survey results suggests.
