A fantastic plan from Slate, here.

One free drink.

Let's take the 10 biggest population centers. In each one, set up a business-type council, full of media types and celebrities, to push voting. In September and October, have them sign up bars and restaurants to put up a red-white-and-blue logo on Election Night. What does the logo mean? With your ballot stub, first drink is on the house. Soon everybody will want to have a logo, the way in the New Deal, businesses showcased the Blue Eagle. Put the word out on college campuses. Get them to compete to throw the biggest party. Pump it up, the way we've done with Halloween.

Registration lotto.

Each state has a special drawing. Anyone who registers to vote is automatically entered. (The number that's drawn will be a voter-ID number.) Set the pot at 10 percent of all the dough Bush raises in your state. Ads can remind people, "But to play, you gotta vote!" This can also make people aware of the last day to register to vote, which is usually 30 days before Election Day. As the deadline nears, the ads can say, "Last chance to play Registration Lotto!"
