True, absentees aren't counted immediately unless within MOE, but eventually all votes are counted for final tallies by law.
Significance of absentees is the TREND, which shows Rs having much larger turnout than 08 (i.e., 2010 levels) and Ds having much smaller turnout (i.e., enough to, say, lose OH by 4 points).
Fixed it.

It's not a theory and it need not be a conspiracy.
It's easier to discard or misplace votes before election day. That's a fact.
