In Ohio in 2008, there were on election day 8 million registered voters who could have ALL voted if they’d just gone to the polls.
In Ohio in 2008, there were only 5.5 million who actually voted. IOW, 2.5 million REGISTERED voters did not vote.
We didn’t lose Ohio in 2008 because of a few percentage points of undecideds. We lost Ohio because of a totally crappy ground game.
Registered voters aren't necessarily "likely" voters, for a multitude of reasons (e.g. moved away, passed away, too busy, or just don't care).
It would be counterproductive to write off the undecided but "likely" voter.
We lost Ohio because of a totally crappy ground game.
No doubt that contributed (along with "Bush Fatigue", Afghanistan & Iraq, unbeatable enthusiasm for the Obamasiah, "white guilt", etc.).
