I also disagree that there's a sizable group of undecided voters anywhere. Sure, many groups claim to be undecided or non-committed. But that is just political pander begging. The people have made up their minds already. But they want to tell people that they can be convinced in order to get what they want.
Political power, influence, the ability (perceived or real) to make a difference in the election... is not uniformly distributed. The louder people get more power, living the a swing state gets more power, and the willingness to say you are "undecided or persuadable" to anyone with a camera... gives you more power.
They think politicians will listen more, pander more, and they'll get the attention they want,... if they say they're "undecided". And often, they are correct.
The concept of a 'voter's decision' is nebulous enough prior to the election that they can easily convince themselves that there is sufficient doubt to justify the undecided label. But in reality, they are suppressing what they know. They know already who they are voting for.
