Not to encourage Dan, but Alternet has a good article titled Are Young People Too Smart to Vote?

Other necessary changes include instant runoff voting, Election Day as a national holiday, Election Day voter registration (Prop. 52 on the California ballot) and public financing of elections. Not surprisingly, nations that employ these practices enjoy much higher rates of voting among all people, including young people, poor people, and others who are left out of our political system.

More than adults, young people seem intuitively to recognize that our political system is broken. And they register their awareness on Election Day by not bothering to participate in what to them is a pretty meaningless exercise. So when you see the low numbers for voter turnout this time, don't think of it as apathy. Think of it as the wisdom of youth.

I think Instant Runoff Voting is a great concept. It's already used in a number of places.

How does it work? Voters rank candidates in order of choice: 1, 2, 3 and so on. It takes a majority to win. If anyone receives a majority of the first choice votes, that candidate is elected. If not, the last place candidate is defeated, just as in a runoff election, and all ballots are counted again, but this time each ballot cast for the defeated candidate counts for the next choice candidate listed on the ballot. The process of eliminating the last place candidate and recounting the ballots continues until one candidate receives a majority of the vote. With modern voting equipment, all of the counting and recounting takes place rapidly and automatically.

If we used it everywhere, I could vote for the Green or Working Families Party candidate, and put the Democrats' candidate second. It would allow me to register my desire for alternative parties without being a "spoiler".
