On Monday, the day before Election Day, radio streaming aggregator and mobile service TuneIn made public a graphic showing "listener engagement" by political leaning across nine "toss-up" states during October.
Interestingly, (as Audio4Cast's Jennifer Lane points out today), the graphic is remarkable in that in all but two of the states won by President Obama, people spent more time, on average, listening to programming classified as "liberal" than to "conservative" programming. (Note, this assumes that Florida ends up in Obama's column.)
Only Nevada and New Hampshire saw slightly more conservative "engagement" (as TuneIn calls it) yet were captured by Obama. North Carolina, which went for Governor Romney (but Obama in 2008), had more listening to liberal programming.
Overall, average daily listening for the month tilted more towards liberal programming (that is, the chart uses the DNC symbol of the donkey, so we assume TuneIn means "liberal = Democratic"): 86 minutes per listener to 76 minutes per listener for conservatives/Republicans. Iowa and Florida, the states with the highest margin of "liberal" listening over "conservative" listening, also had the most overall listening (over 200 minutes daily per listener in Iowa's case).
