After a long work day, most people just want to have dinner, slump on the couch and watch their prime-time programs. Instead of airing new episodes that November evening of Election Day, all stations should instead air re-runs with commercial breaks telling people to go out and vote.
Polling places should set up barbecues for everyone who voted: grab a free hot dog or burger. Even free popcorn can be inexpensive, car washes do it!
Trap parents by offering face painting and bounce houses for kids; the complaining of kids could be very influential, too.
