I found this:
“As a result, while the number of absentee ballots cast by Florida Republicans in 2008 beat the Democratic number by some 15 points, this year that gap narrowed dramatically to fewer than 5 points. In fact, the total number of absentee ballots cast in Florida so far is more than 2 million, up 8.7% from 2008. That brings the early-voting total in Florida (in-person and absentee ballots) to almost 4.5 million more than in 2008. (In 2008, Florida had 11.2 million registered voters; this year its 11.5 million, so the total early-voter share of the state electorate is still about the same, around 38%.) In all, Democrats have cast almost 250,000 more early votes than Republicans have, and that number could climb when all the outstanding absentee ballots have come in. Obama likely ends up with an early-vote lead in Florida of about 5 points.”
You’re referring to 2012. When including early and absentee voting, there were more Dems. Yet Romney only lost by 0.9%.
