Were there any undecided voters

The Annenberg Center at the University of Pennsylvania doesn't seem to think so. CQ Today's Midday Update (free email service) notes this interesting development:

For all the talk about wooing the undecided voter, a new survey shows very few Americans who cast ballots in the Nov. 2 presidential election ever considered voting for the other guy. And those who did pretty much offset one another. The University of Pennsylvania's National Annenberg Election survey shows just 16 percent of those who voted for George W. Bush said there was "ever a time" when they thought they would vote for Democrat John Kerry; 15 percent of Kerry voters said there was "ever a time" they thought they would vote for Bush. Adam Clymer, political director of the survey, said the data vindicated the parties' campaign's strategy of playing to their base and spending relatively less time and money on undecided voters or soft supporters of the other candidate.

Does this mean that all political theory will go out the door? Is there no sich thing as "undecided voters"?

More realistically, the lack of so-called "undecided voters" could be unique to the Presidential election of 2004 or possibly elections in which a President is running for reelection. In 2008 -- the first year since 1952 in which the sitting President or Vice President is not running -- look for the number of these voters to increase dramatically.
