Since early voting began in Iowa on September 27, more than 264,000 votes have been cast, 15.6 percent of the total 2008 turnout statewide, and the early returns seem to be breaking hard for President Obama.
50.2 percent of the ballots cast belonged to registered Democrats; only 29.8% were cast by registered Republicans.
With just under three weeks until election day, Iowa is already well over halfway to matching its early voting tally from 2008, when about 448,000 people voted early.
Recent history suggests that high early voting turnout may crucial to an Obama victory in Iowa. In 2008, when early-voter turnout broke 46/31 in favor of Democrats, Barack Obama was able to take Iowa by a double digit margin despite being beaten narrowly by John McCain in votes cast on Election Day.
It is unclear whether Obama will enjoy such a comfortable lead heading into November 6 this year: 19.9 percent of early ballots were cast by registered independents whose support may have shifted away from the president to some degree in this election cycle.
