This map is pretty sweet. It shows percentages of registered voters, percentage of voters that went for Bush and Gore in 2000, income levels, and more for every voting precinct in Missouri.
If you zoom in on the Truman campus, you'll notice that it has 80-100% inactive or unregistered voters. I find it pretty damn hard to believe that all of them used absentee ballots to vote at home. So this tells us that there are easily 2000 students on the Truman campus that need urging to get out and vote.
And since young people, even on a conservative campus, typically split largely democratic, we can make a huge difference.
