A couple statistics stand out to me.

According to Gallup's mega-final-ultra poll out Sunday evening, 30% of registered voters in Florida have already voted, either through early voting or by absentee. Of those who have already voted, Kerry leads President Bush 51% to 43%.

According to the Des Moines Register poll out late Saturday evening, 27% of Iowa adults have already voted. And among those Kerry leads 52% to 41%.

Both numbers seem good for Kerry -- though they may mean a lot of different things.

But, as long as we're asking questions, if these are people who've already voted, shouldn't the number add up to 100% or close to it? Are the remainder folks who wouldn't answer? Or have they already voted but moved back into the undecided column? Or they've forgotten? Someone help me with this ...
