The Miami Herald's Marc Caputo (emphasis added) on the continued relevance of the Jewish vote in Florida.
About 336,000 Jewish voters cast ballots in Florida in 2008, 252,000 for Obama and 84,000 for McCain (based on a 75-25% split, which accounts for the slightly more Republican flavor of Florida Jewish voters as expressed in the previous state exit poll compared to national results).
If Obama's Jewish support drops to 68 percent in Florida, he loses 23,520 votes.
That's not a huge amount in an 8.4 million-voter election like 2008, but it accounts for almost 10 percent of Obama's victory margin.
Gallup currently has the race for the Jewish vote, nationally, at 68%-25% in Obama's favor.
