Wow. I am not a likely voter (5). I recently moved and until a few hours ago (when I recieved my sample ballot) I did not know where my polling location was, nor had I ever been there before. So I answered the survey as I would have yesterday. Yesterday I was not, today I am (6)!
Scoring below 7 does not mean that someone is not considered a likely voter.
Gallup assumes 60% turnout in this election and they take the top 60% of their sample as scored 1-7 to determine the LV results.
