I’ve created a quick spreadsheet from the early voting turnout results posted at Cuyahoga County, OH (hat tip to Michael McDonald).

To date, there are differences between D’s and R’s, but a noticeably lower return rate among non-affiliated voters, when ballot returns are calculated as a percentage of ballots requested.

Overall, 29.19% of absentee ballots requested have been returned; 30.98% among registered Democrats, 31.67% among registered Republicans, and 20.81% among non affiliated voters.  The spreadsheet is attached to the crossposting at http://earlyvoting.net.
